I want to calculate p-value using lmtest::coeftest
and I used this:
lmtest::coeftest(modelmucocon)
and then, this message appeared:
Warning in sqrt(diag(se)) : NaNs produced Warning in cbind(est, se, tval, pval) : number of rows of result is not a multiple of vector length (arg 2) Error in dimnames(x) <- dn : length of 'dimnames' [2] not equal to array extent
