Clinically significant change criterion calculator

Mounted by Chris Evans in 1998, replacing it with the link below 5.iii.24.

The original application gave all three of the criteria for a CSC, i.e. criteria a, b and c. I am now so convinced that the a and b are really hopeless criteria that I no longer support then at all. (Not like me not even to support them for historical interest but that only tempts people!)

So now go to https://shiny.psyctc.org/apps/CSC1/. Allow a few seconds for it to load: quite a lot is going on in the background on a not very powerful server!). That gets you to a shiny app that will do what this old form did and give you criterion c given help-seeking and non-help-seeking mean and SD values. It also gives you a pretty plot of the Gaussian logic behind criterion c.
