- subset command to allow logical definition of subsets eg sex=2
- empirical logit transform for Scatter and Matrix graphs with Binomial errors
- split Define dialog into two dialogs creating Fit Options dialog which contains settings not defining the generalised linear model
- made a lot of changes to the Graphing routines to make sure everything is in the right place and there are no cosmetic problems. Changed plotted symbol sizes slightly and added new very small symbol size
- vertical axis label in graphs should now print as rotated text on postscript printers not as a bitmap
- fixed bug which caused display errors or crash when importing text and too many errors
- improved behaviour of graphs when data is changed by hiding them and then redrawing only when graph is shown and checking that graph contains columns which were changed
Version 4.0.3
- fixed bug which turned missing into zeroes when data from other applications (not from GLMStat) which contained only integer values is pasted into a real column
- allowed real data to be pasted into integer columns if it contains data which contains only integer values (ie 1.0,2.0 etc)
Version 4.0.2
- no changes, upload only to fix info-mac archiving problem
Version 4.0.1
- fixed crash which often occurred when closing documents if multiple documents open
- fixed crash if auto-create graph involving Response was selected
Version 4.0
- Missing values
- Info window to allow storage of text information about data
- slice command to turn a continuous column into an integer
- sorting of data
- multiple data windows
- copy and paste in data sheet is to/from a resource rather than text so that accuracy is maintaned
- slight improvement to Test command to allow models with Offset
- Matrix graphs now allow Jitter and Lowess (good for showing off G3 powermacs)
- Open command now allows openning of both GLMStat and Text files and automatically determines if text files have a column heading line or not
- in scatter plots if points overlap then no attempt to draw in gray
Version 3.2.3
- fixed bug which caused heading of Pearson to be displayed instead of Deviance in Test command with scale estimated by Pearson Chi-sq
- fixed crash that occurred when fitting Poisson models with a linear and factor interaction
- fixed problem on systems without Internet Config 2.0 by reading the instructions and then including the correct file
Version 3.2.2
- fixed bug which caused error in Test command when rows are excluded
Version 3.2.1
- fixed bug which caused error in calculation of deviance in Test and Effects commands for Poisson models where degrees of freedom are corrected for empty cells
Version 3.2
- Effect test (ie calculate test for change in deviance from removing top level terms from model
- allow display of title as Sum of Squares instead of Deviance for Normal models
- able to include or exclude a row or rows from an analysis
- much of the changes have been made to allow missing values
- removed Show All command for Graphs. Points within the current subset only
will be shown. Points with weight=0 will return missing for residuals.
- allowed saving of contents of Graph and Results windows as files
- when an observation is weighted out the residual will now be shown as missing - for standardised residuals if the leverage is one or the scale is zero the residual will also be shown as missing
- fixed some cosmetic problems
- changed "Scale and Test" to "Scale estimated using" in Define dialog and Test now performed only using Deviance but with scale estimated by Pearson Chi-sq if required
- degrees of freedom are now correctly calculated for Poisson models with empty cells ie if the marginal sum for an estimate is zero so the fitted value will be zero and the actual value is zero (which it will be if the marginal sum is zero) then the observation is removed from the data set.
