Hi Bert: I thought in centering Baci variable, but I wouldn`t like to draw a conclusion based on the scaled response variable. On the other hand, if I had to center the explanatory variable, that would be great, but I cannot, as it is a factor. Thanks a lot for your time. I really appreciated yo

Re: [R] table , exclude - count the frequency in a data frame but exclude one value

table converts its non-factor arguments to factors using the exclude argument that you supply. If you want the arguments to be handled differently, then convert them to factors yourself, in the way you want. E.g., > with(df, table(x=factor(x, exclude=1), y)) y x 1 2 3 2 0 1 0 3 1 0 0 >

Ok. I`m trying to run a Poisson glmm with an observation-level random intercept. But I`m getting the following error for the 'Baci' variable: 'Error: (maxstephalfit) PIRLS step-halvings failed to reduce deviance in pwrssUpdate'. I guess this message is because the baci variable is not a an intege

Please respond to the list. It will be obvious why in a second. That's not my threshhold! -- it's R's. Your numeric integers cannot be exactly represented as integers in R. Period. Maybe there are special packages for extended arithmetic that can do this. but someone else would have to help you th

Re: [R] From NUM to INT

That is the "impossible" case, since R integers are 32 bit signed (~2×10^9) even in 64 bit R. You can Google for "R arbitrary precision" and look for packages like Ryacas, bit64 or gmp. However, having such large integers stored as integers would not be necessary for most statistical analyses so

No. >From ?as.integer: "Note that current implementations of R use 32-bit integers for integer vectors, so the range of representable integers is restricted to about +/-2*10^9: doubles can hold much larger integers exactly. " Cheers, Bert Bert Gunter "The trouble with having an open mind is t

This is a quadratic programming problem that you can solve using either a quadratic programming solver with constraints or a general nonlinear solver with constraints. See https://cran.r-project.org/web/views/Optimization.html for more info on what is available. Here is an example using a nonline

Re: [R] Linear Regressions with constraint coefficients

If the slope coefficients sum to a constant, the regressors are dependent and so a unique solution is impossible (an infinity of solutions would result). So I think you have something going on that you don't understand and should consult a local statistician to help you formulate your problem appro
