hep on arithmetic covariance conversion to log-covariance
...,-0.0136,0.0026,-0.0001,0.0001,0.0008,-0.0015,-0.0011,-0.0370,0.0008,1.0466,0.7208,-0.0455,-0.0136,-0.0015,0.7208,1.1717,0.0346,0.0026,-0.0011,-0.0455,0.0346,0.0348),byrow=TRUE,ncol=5)
which I would like to conver to a covariance matrix from a log return. My solution probably should be similar to aprevious post at http://stackoverflow.com/questions/7663690/log-covariance-to-arithmetic-covariance-matrix-function, but the other way around?
I would greatly apreciate the help,
thanks,
Andras
