Changes for version 0.02 - 2017-02-10
- croak on finding unequal N, or zero within- or between-group observations, ahead of chiprob_test (avoiding divide by zero error).
- correcting POD for chiprob_test regarding returned values when called in list context.
- "repeatedly measured" rather than "dependent" variables used to describe the test in POD.
Nonparametric analysis of variance by ranks for trend across repeatedly measured variables (Page and sign tests).
