Subject: Creating a correlation matrix from a vector
I'm looking to create a correlation matrix, but I have already obtained the
correlations, which are stored in a vector. (Basically, I'm running a
simulation which requires a correlation matrix, but I am simulating the
various correlations.)
My aim is to create a function that can take the vector, and fit the values
into their respective locations in a correlation matrix. (The correlations
are ordered as if working along the upper triangle of the correlation matrix
row-wise.)
The initial step in the function was to create a diagonal matrix of length
n, (n being the number of factors) and then add the correlations at each
level using a for command.
Thanks
