<> To implement Kit`s proposal, Pascal could qualify his -cmp- call via *********** if runiform()<.01 *********** Since he said he has 10.1, this should work. HTH Martin -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Kit Baum Sent: Sonntag, 16. Mai 2010 13:29 To: statalist@hsphsun2.harvard.edu Subject: re:st: RE: Error Message: r3900 - Problem with Memory of my Computer system ?! <> Pascal said Martin gave me the extremely helpful advice to use the "cmp" command to implement a three-stage selection model. So far it works fine. However, when modeling the three-stage system with two selection equations and 1,000,000 observations I get the following error message when cmp tries to estimate the combined model: <istmt>: 3900 unable to allocate real <tmp>[1224521,46] r(3900); I already allocated the maximum memory (1000m) and matsize (10,000) to STATA. I still get this error message. So you have an idea how to solve the memory problem? By my calculations that single matrix is about 4.2 Gb, so unless you have access to a system where you can allocate 5 or 6 Gb to Stata, you have no hope of solving this problem. What happens if you try to estimate the model with 10000 observations rather than a million?
