This function pools columns of a 2xK contingency table (if needed, ie if low numbers present)
pool2K(M, low = 2)
| M | is a 2 by K contingency table (or a K by 2 table) |
|---|---|
| low | is a threshold for low expected numbers; default is 2 (if this argument is big enough, the table is pooled down to 2 x 2; if this argument is 0, the table is not pooled) |
This function returns a matrix with the pooled contingency table.
