[R] Generate normally distributed correlation matrix

[Richard Wang]

Hi, 

I would like to ask a statistics questions.  One way to generate a correlation matrix with normally distributed entries is by generating a matrix A with uniform or normal rows.  Then normalize each row to get B.  Then B times transpose B is the desired matrix.  However, the standard deviation of the entries is not large enough for my purpose.  Is there a method to generate a normally distributed correlation matrix with a controlled (larger) standard deviation?

Thanks for any help.

Best,
Richard
