However, I can't compute right critical value for multivariate normal distribution which I want. I don't know how to solve my question. I send my question in the file. Would you help me to solve it, please? My English is not very well, but I appreciate you very much.

one possibility is to invert the P-value function `pmvnorm' from
package `mvtnorm' using `uniroot' - There is FORTRAN 90 code solving this
problem available from Alan Genz' homepage at
