Hello,
I am a french student and i am studying an article where there is a SAS/IML code.
In this code, DES is a matrix of parameters, DELTA and EST are vectors. Delta={0,0,0,0} and EST is the vector of parameter estimates.
We calculate lambda=exp(DES*(-EST)) so lambda is a vector.
Then, to calculate the exposure at different time intervals (4 intervals) until time t=0 :
lambda_delta_t1=lambda # DELTA
In my application, # don't work because lambda and delta are vectors. I don't know how to do and I don't understand.
Thank you
