- Can read EXP formatted data files (new form of EpiData XML data structure)
- Odds Ratios are now Standard Mantel Haenzel with Breslow CI's
- For Exact Odds Ratios option /oex should be used - to get same results as previously
- RunCharts added counts and skipped points
-Histogram Now groups data into bins.
- /CLOSE added to Generate command.
- Added: /FONTSIZE and /SUBFOOT added to graph commands.
- Xbar-S Charts - Common Sigma-bar shown Instead of varying by subgroup size
- Documentation in commands.htm clarified and extended
- Run Charts - expected runs for observations: 31-40 added
- Documentation in commands.htm clarified and extended
- Table Statistics extended with Confidence Intervals for Gamma Coefficient
- Added: Graph dialog moved XLabel to "Variables" tab page.
- Add: Error is printed in PChart if Denominator is larger than Nominator.
- SPC template extended with Xbar-R
- Gchart - value of first data point indicated on X-axis
- A first b165 downloaded April 1st-Apr 2nd did not have this feature
- Using freeze: /F= with a date type x-axis variable now uses data point no. from /F
- /f freeze option functioning in pchart, uchart, xbar and gchart
- See all changes below in builds since last public release
- Result Variables for Means command
- Default windowing changed to width 700px
- Added result variables for means
- Changed default decimal count for MEAN vector created by aggregate.
- Option /adj documented for lifetable
- Xbar adapted to accomodate where a given x-value contains only one observation
- Option /noXlabel /noYlabel added to all graphs and graph dialog
- Graph dialog rewritten
- SPC command options extended - see command reference
- SPC graph commands rewritten to a new common internal form
- Added SPC template (spc.htm) to graph sub menu.
- SPC command syntax simplified (no need for time variables)
- Added preliminary SPC template to testdata (spc.htm)
- New definitions of set commands, can be focused to each command
- Added preliminary SPC template to testdata (spc.htm)
- First implementation of 2 additional SPC warning tests (test4 and test5 in Ichart)
Bugs Fixed :
- Mismatch of /subfoot and /Noinf in SPC graphs leading to non-showing of estimates for periods (solved)
- Graph dialog reshaped to show weight variable always (was sometimes hidden)
- Removed Sigma3 from legend in runchart command.
- Freq sorted incorrectly by default, and using /SA or /SD.
- Variable name with "if" in, cause pre-processor to incorrectly insert "set option" text the wrong place.
- Labelvalue command gave no error with incorrect construction.
- Use of /W in tables command deleted wrong variable in some instances
- TAble dialog /RR option adapted (but still not working with /FV)
- SPC run charts - fixed error, expected runs included median
- Frequency table sorting not working
- Gamma coefficient not printed in certain tables
- Selection of RR in table dialog
- Internal error in handling number of records
-Could lead to failure in merge (and other special cases)
- The X-axis on dotplots only used 75 percent of the space
- Incorrect MEDIAN in Runchart with few decimal points in measurement.
- /SAVE in graphs did not respect given path
- XBar failed with subgroup count > 20 due to factorial miscalculation.
- The ½ point offset for sigma/center lines in SPC charts was incorrectly calculated in some special cases.
- Fixed: Issue where a value of 0 (zero) in the denominator of PChart would crash program.
- Table crashed if multiple valuelabels existed with same labels, but different value.
- Incorrect MEDIAN in Runchart with few decimal points in measurement.
- /SAVE in graphs did not respect given path
- XBar failed with subgroup count > 20 due to factorial miscalculation.
- The ½ point offset for sigma/center lines in SPC charts was incorrectly calculated in some special cases.
- Date variable accepted for aggregating in xbar spc charts
- Sparse data table problem with correct cell allocation (stratified tables)
- Other minor bugs fixed - see Mantis database
- No data exception with bar and histogram
- Reference to old variable names after close (fixed)
- Other minor bugs fixed - see Mantis database
- Text on interface of SPC submenu adapted
- Issue with exit
- Parsing of certain statements
- Several minor issues (aggregate variable naming,percentiles ...)
- Several minor issues - see Mantis system
- Fixed width of browser columnds to accomplish dates and labels (incl. update)
- Fixed menu issue when using EpiData Analysis in Linux under "Wine"
