[R] maximum likelihood convergence reproducing Anderson Blundell 1982 Econometrica R vs Stata

Dear R-help, I am trying to reproduce some results presented in a paper by Anderson and Blundell in 1982 in Econometrica using R. The estimation I want to reproduce concerns maximum likelihood estimation of a singular equation system. I can estimate the static model successfully in Stata but for

[R] nndist R vs. ArcGIS

Can anyone tell me why I would get different average nearest neighbor values for the same set of coordinates between ArcGIS 10 and R? Sometimes the difference in distance is over 1.3 km. Alexis -- View this message in context: http://r.789695.n4.nabble.com/nndist-R-vs-ArcGIS-tp3442375p3442375

[R] Offset in glm poisson using R vs Exposure in Stata

R-helpers, I am hoping to find someone who uses both R and program Stata for GLMs. I am a beginner R user, finding my own way through; learning code etc. at the same time as learning the statistics I need to complete my project. What I have is the code from Stata and am trying to reproduce
