Displayr

User wants to do significance testing for tracking studies that only compares to the prior wave, but their waves are irregular. It would be immensely helpful to our clients with tracking studies if there was an option (arrows and font colors) to compare against the prior category only.

In Q you can customise Column Comparisons to compare specific columns ([ https://wiki.q-researchsoftware.com/wiki/How_to_Specify_Columns_to_be_Compared|https://wiki.q-researchsoftware.com/wiki/How_to_Specify_Columns_to_be_Compared ]). However, this functionality has yet to be added to Displayr which only allows default Column Comparisons with no means to customise.

You should be able to do everything in Q for stat testing in Displayr too.
