...s me some NaNs for errors, whereas the one from optim gets me numbers for all parameters. If I look for eigenvalues for numDeriv::hessian, I get two negative numbers (and six positive - I'm fitting to eight parameters), so does this mean that optim hasn't converged correctly, and has hit a saddle point? If so, is there any way I could assist it to find the minimum? Thanks, Jon Phillips

I'm currently running Centos 8 off an SD card. It, unlike F32, lets me use my monitor's full 1440 x 900. Both seem to use defaults and EDID, but F32 gets it wrong and saddles me with 640 x 480 when I can find the incantation to have it run at all. The configuration files and directories I can find are pretty much empty. How do I add --configure to the Xorg command line? 'Tis my understanding that would generate a configuration file that I could port to F32. --...

Dear R : Sorry for the off topic question, but does anyone know the reference for the -2 Ln Lambda following a Chi Square distribution, please? Possibly one of Bartlett's? Thanks in advance! Sincerely, Laura Holt mailto: lauraholt_983 at hotmail.com

Apologies if this is a FAQ. We are saddled with some directories full of production image files that number in the hundreds of thousands to the millions. (Yes, I know this is bad.) They reside on a couple of Win 2003 boxes that are flaky and unreliable. I was hoping to copy them over to a Linux box running samba but it is taking for...

...d multiple-contrast hypotheses based on Wald test statistics. The hypothesis tests incorporate small-sample corrections that lead to more accurate rejection rates when the number of clusters is small or the design is unbalanced/leveraged. Tests of single regression coefficients use Satterthwaite or saddle-point corrections. Tests of multiple-contrast hypotheses use an approximation to Hotelling's T-squared distribution. Methods are provided for a variety of fitted models, including lm(), plm() (from package 'plm'), gls() and lme() (from 'nlme'), robu() (from 'robumeta'),...

...d like to fit Logit models for ordered data, such as those suggested by Greene (2003), p. 736. Does anyone suggests any package in R for that? By the way, my dependent variable is ordinal and my independent variables are ratio/intervalar. Thanks, Iuri. Greene, W. H. Econometric Analysis. Upper Saddle River, NJ: Prentice Hall, 2003

I have tried installing tasbooks 2 from CD and the installer ran fine but no icon or star file appeared after finishing install. Does anyone have any idea how to get tasbooks running with crossover? Thanks for your help. P.S. the software is working fine with parallels. Since I am on a trial version of parallels (and crossover for that matter) I need to decide which on use in future. I would

Hi, I am trying to fit a 4p logistic to this data, using nls function. The function didn't freely converge; however, it converged if I put a lower and an upper bound (in algorithm port). Also, the b1.A parameter always takes value of the upper bound, which is very strange. Has anyone experienced about non-convergent of nls and how to deal with this kind of problem? Thank you very much.

Hi all, I use Luke's "::" hoisting trick often. I think it would be fantastic if the JIT just did that for you. The main trouble, for me, is in code I don't own. When common Bioconductor packages are loaded many, many base functions are saddled with this substantial dispatch and "::" overhead. While we have the hood up, the parser could help out a bit here too. It already has special cases for "::" and ":::". Currently you get the symbols "pkg" and "name" and have to go fishing in the ca...

Dear All, I have been trying to to do this for a few days now. I can generate persp plot OK and can generate it in colour using the command persp(x,y,z,col=terrain.colors(20)) However, I was wondering if it is possible to shade the 3d surface like a contour plot. i.e. black for large z, white for small z, say Thanks in advance Colin
