Dear programmer
First, I would like to thank for making PSPP available for all.
I have found some incorrect analysis in PSPP statistics program.
When I use analysis->crosstab and choose to calculate risk . The result show odds ratio and risk ratio with confidence interval. The upper and lower confidence interval are the same which are wrong.
