Hello I have a question regarding SAS’s PROC MODEL: If I define a variables starting value for the iteration process, PROC MODEL uses it for the first observation of the processed dataset. For the next observation it uses the final value of the previous iteration process to start the next iteration process. In some cases this leads to trouble because the function I use has a singularity. So how can I force proc model to use assigned starting values for the iteration process for every observation! Thank you in advance. Regards, Klaus
