Hi there! I'm not sure I can create a minimal example of my problem, so I'm linking to a minimal .RData file that has only two objects: obs and exp, each is a 6x9 matrix. http://dl.dropbox.com/u/10364753/test.RData link to dropbox file (I hope this is acceptable mailing list etiquette!)
Here's what happens: > obs[1, 1] [1] 118 > exp[1, 1] [1] 118 > obs[1, 1]-exp[1, 1] [1] 2.842171e-14 Problem is, both obs and exp should be identical. They are the result of a saturated loglinear model, and I've run the same code across about 400 tables, all of which result in sum(obs-exp)=0, except for this one. I can't figure it out? Anyway, I need help understanding why 118 and 118 are not really the same. I appreciate some may be wary of downloading my .Rdata file (I'm on ubuntu if that's any consolation), but I don't know how else to ask this quesiton! Thanks!
