Dear All,
I still can't find the error. It seems that a negative or zerovalue is passed to the logarithm
function. The logfile says:
NOTE: Invalid argument to function LOG at line 136 column 10
Line 136 is:
LL = log(Px1 * Px2 * Px3 * Px4 * Px5 * Py1 * Py2 * Py3 * Py4);
The data step code returns the following meassage:
LL=. _ERROR_=1 _N_=1
So, it should be something very easy. But, I can't see it.
I appreciate every comment very much. Thanks to all of you, especially to Dale.
Best,
Mene
