Date: Fri, March 19, 2004 10:42 am Dear All: I wonder if any of you could suggest a publication or a text-book that would help someone WITHOUT much math. background,to understand the estimation methods(the first order, FOCE, hybrid etc.,).The Users guide seem a little daunting, and my search for a basic work to understand the concept and applications has not been fruitful. Will be grtaeful for any sugesstions. Thanks a lot Ram
