...Does anybody have such a code they can share or know a library in which I can find this function? Basically I have a number of time series which I need to check for persistence. One other test I can use is the runs test in the tseries package. Any help will be greatly appreciated. Thanks a lot, Rauf Ibrahim R. [[alternative HTML version deleted]]

Dear All I want to generate multivariate normal data in R for a given covariance matrix, i.e. my generated data must have the given covariance matrix. I know the rmvnorm command is to be used but may be I am failing to properly assign the covariance matrix. Any help will be greatly appreciated thanks. M. R. Ahmad

...I am studying this link ( http://xapian.org/docs/bindings/csharp/) - To implement improvements in the current bindings. Would you please refer me some material to study in this regard? Also what kinds of binding improvements are required by Xapian? I look forward to your response.

Dear All I need to generate multivariate NON-NORMAL data in R, which follows a given mean vector and covariance matrix, say multivariate exponential data. How can I do that? Best regards mra

Dear All I am kind of stuck up with a code a part of which seems to be causing a problem, or at least I think so. May be the community can help me. It’s simple but I suppose I am missing something. I generate a data matrix X, say of order n*p, where n represents independent row-vectors and p correlated col vectors. Let the row representation be X = (X’_1, . . ., X’_n)’. I generate the
