correlation with ties & multiple comparisons problem
...from the ltm-package. Unfourtunatly this results in more than
50 warnings like this due to ties:
In cor.test.default(mat[, index[i, 1]], mat[, index[i, ... :
Cannot compute exact p-value with ties
I have now two question:
1. Is there any way to calculate a exact p-value for data that is not
noramlly distributed?
2. Do have to correct for multiple comparisons in this case as I am
practically testing each possible pair of the 40 variables?
Many thanks for your help!
