SOFA Statistics Changelog

New in version 1.4.5

August 17th, 2015
  • Box plots can be displayed with different outlier and whisker display options.
  • ODS importing can now cope with repeated column names.
  • Better error message when unable to get regression line details because of limited variability.

New in version 1.4.4 (May 11th, 2015)

  • Mac users can export output in PDF format (and PNG depending on version of OS X).
  • Added new monochrome theme.
  • Chi Square proportions output much easier to interpret successfully.
  • The name of the grouping variable is now displayed when running comparisons of groups e.g. Country if comparing Italy and Germany.
  • Exporting to spreadsheet detects if too many fields for xls output and informs user that only csv will be generated. Also truncates table name so worksheet name not too long.
  • Import dialog only displays file types suitable for importing.
  • Added message to let user know spreadsheet creation being skipped if no report tables to export.
  • More user help on need for raw data (not pre-summarised) and long-format vs wide-format data as appropriate.
  • Code reorganisation to make it possible for SOFA to be called in GUI form by external code GUI code.
  • Scripts are now easier to use for standalone purposes.
  • Added note about treatment of datetime data as categorical by SOFA for purposes of statistical tests.
  • When exporting to spreadsheet and csv changes reserved sofa_id field name to was_sofa_id so it is OK to reimport after changes.
  • More informative for larger range of potential problem e.g. database engine not functioning.

New in version 1.4.3 (December 12th, 2014)

  • Can import tab-delimited data.
  • More options for attractive charts and reports. Three new themes available – sky, prestige (screen), and prestige (print).
  • Better support for automation (i.e. headless, running without GUI) esp in international context.
  • Exporting to spreadsheet now relies on more robust code library (xlwt)
  • Easy to select or deselect lots of row stats measures at once.
  • Faster opening in many cases.
  • And the bug fixes:
  • Minor tweak to PostgreSQL plug-in to handle timestamps without timezone.
  • Resolved bug when SQLite numbers are stored in a non-numeric field and processed for Chi Square test.
  • Importing csvs now copes better when only missing vals in sample of a field. Gives user the choice.
  • Fixed bug when doing a Row Stats table with a rows variable e.g. by Gender and some of the fields can’t be calculated for some of the row categories.
  • Headless importing now works in the event of inconsistent data types in fields.
  • Headless importing now reads entire dataset rather than a sample to avoid need for (human) decisions.
  • Scripts no longer rely on translated arguments. Much safer to use on other machines with different locales.
  • Fixed circular import bugs which only became visible when other bugs occurred.

New in version 1.4.2 (February 10th, 2014)

  • Can export results as high-resolution images (PNG), PDFs, and tabular output as spreadsheets without needing plug-in extension (doesn't work for Macs currently - very sorry :-( ).
  • Can export data tables to spreadsheet without needing plug-in extension.
  • Can backup SOFA data and settings without needing plug-in extension.
  • Variable details content (vdt files) is now sorted which makes it much easier to read and search for items when checking things.

New in version 1.4.1 (February 1st, 2014)

  • Scatterplots now have option of displaying regression line with slope and intercept details.
  • Export output plug-in (proprietary add-on) now gives option of exporting tabular data to spreadsheet.
  • Better positioning of legend in scatterplots made by matplotlib.
  • Tweaked algorithm for getting optimal min and max axis values so more sensible when no variation.

New in version 1.4.0 (December 16th, 2013)

  • Ease of use is one of SOFA’s main goals (along with “learn as you go”, and “beautiful output”). Unfortunately, as new options were added to SOFA for exporting data, the simplicity of the output section of the user interface suffered slightly. New buttons were squeezed in one by one and the interface was getting more and more crowded. Something was going to have to change. And in version 1.4.0 it finally has! – I hope you like the change. It not only removes two interface items but it also adds room for more export options in the future. And there is more horizontal space in the drop-down control to describe each option more clearly and distinctly.

New in version 1.3.5 (October 14th, 2013)

  • Bug fixes:
  • Fixed bug in histogram output when limited data spread. Error caused by miscalculation of significant decimal points required for display.
  • Fixed bug stopping late-added title details appearing when exporting output. The demo output is refreshed first so the source file is forced to be up-to-date. Probably needs a proper tidy-up some day but this works well in the mean time.
  • Fixed bug in exporting to desktop folder in fix_pdf - need to strip end off folder name when no AM/PM under localisation used.
  • Fixed various bugs associated with exporting output. When copying output, message about keeping form open now names form it means (to reduce confusion).
  • Fixed bug when using a project after it has just been deleted (by pressing cancel in select projects dialog after having deleted the currently active project).
  • Fixed bug which meant "Show Results" and "Add to report" options were displayed when setting up a project.
  • Fixed bug when cancelling a variable details selection in a project.

New in version 1.3.4 (July 23rd, 2013)

  • Can make more complex charts and larger series of charts. It is now possible to override the conservative limits on charts e.g. the maximum number of series or charts or clusters. A warning is shown that you may not necessarily produce a viable chart or set of charts. But often it will work so now you get to try and see.
  • Importing now copes with excessively long fieldnames by shortening them automatically (without risking duplicates).
  • MS SQL Server views can now be analysed, not just tables.

New in version 1.3.3 (April 6th, 2013)

  • Improved statistics output footnotes.
  • Borders on bar-type charts are now optional. This can be useful when bars are very short.
  • Chi square clustered bar charts can cope with higher default limits for number of values.
  • Importing field names with more than 90 characters prohibited at the point of import rather than causing problems later.
  • The group by max number of values is now controlled by a single my_globals setting (making it easier to override).
  • The default settings for some remaining max values have been increased.

New in version 1.3.2 (January 28th, 2013)

  • Can backup SOFA data, reports, and variable and project details, via extension plug-in.

New in version 1.3.1 (January 10th, 2013)

  • Adding sum as an option for charting e.g. a line chart showing total income per month by product.
  • Matplotlib scatterplots now have optimal min and max settings calculated for their x-axis.
  • Added footnote to Wilcoxon output explaining that different statistics packages may report the test statistic differently.
  • Misc fixes to chart layout including left margin offset.
  • Easier to add new variable definition files from within dialog for choosing them.
  • Modified recode column labels and help content to reduce confusion about which columns to enter range information into.

New in version 1.3.0 (November 5th, 2012)

  • Added Mode as an option to Row Stats report tables.
  • Line and area charts can show major labels only as an option.
  • Pie charts now have option of displaying count and percentage (not just in the tooltips as at present).
  • Histograms use consistent bins when charted by a second variable.
  • Better placement of y-axis title when wide labels.
  • Pie charts keep consistent colours even if sorted by count rather than value or label.
  • Better message when adding new reports if required subfolder with javascript and background images is missing. Only show message now if a problem.
  • When trying to export report, SOFA checks for expected subfolder as well (otherwise dojo fails for any charts and export fails).
  • SOFA prevents attempt to export report if no report file (yet).
  • No longer displays View or Export Report buttons on Projects dialog.

New in version 1.2.2 (September 20th, 2012)

  • Can import from xlsx.
  • Normality analyses can be included in reports, saved as output etc.

  • Can now sort by individual columns within a data display report table.
  • Report tables of summary statistics e.g. mean, median, sd, now show the measures across columns instead of down rows. Easier to compare results and notice difference.
  • The demonstration tables displayed when configuring report tables now use real data instead of random data if the data source is small enough to make updating fast.
  • The "Show Results" button becomes "Add to Report" when report tables are able to use live data for examples (and the "Add to report checkbox" is hidden).
  • Add to report now defaults to False and remembers the last setting throughout the user session.
  • Repositioned some standard GUI items to increase logic of placement and speed of use.
  • Added IQR (Inter-Quartile Range) to the Row Stats Table.
  • Can now do a boxplots of a single variable (not requiring a variable for it to be By).

  • Smarter column resizing.
  • CSV importing correctly identifies if file has a header more accurately if only one column (and thus no delimiter identified initially).
  • Adjusted chart sizings to be more rational and less magic.
  • Better width settings for dojo histogram output when lots of bins (prevents x-axis labels bunching up).
  • Row stats tables show "Not calc" instead of nan (not a number) when appropriate.

  • Added ability to chart percentages as well as frequencies.
  • Chart series now all have consistent y-axes (trellis style).

New in version 1.1.5 (May 28th, 2012)

  • Charts now have the option of rotated (vertical) x-axis labels. This can be useful for longer labels.
  • Scatterplots now focus on the data better by starting axes just below the minimum x and y values of the data unless the value is close enough to 0 to make it worth using 0 anyway.
  • Numeric values are right justified in data tables.
  • Kurtosis values in the normality test include the Fischer adjustment (subtracting 3).
  • Duplicated field names in imports are given unique suffixes and allowed (now that they are unique).
