geoRglm with factor variable as covariable
Dear R users. I'm trying to fit a generalised linear spatial mode using the geoRglm package. To do so, I'm preparing my data (geodata) as follow: geoData9093 = as.geodata(data9093, coords.col= 17:18, data.col=15,* covar.col=16*) where covar.col is a factor variable (years in this case 90-91-92-93)). Then I run the model as follow: / model.5 = list(cov.pars=c(1,1),

psigamma derivative
Hello, I am trying to find a hessian matrix that involves log(gamma(1/p)) second derivative, p being one of the parameters of the function. I am using a function "deriv" with the hessian=TRUE option, but psigamma is not on the list of derivative functions. I know that it is possible to use 'psigamma(p,deriv)', but it doesn't work with 1/p. Does anybody can help with this?

A question about GRAMMAR calculations in the FAM_MDR algorithm
Dear R developers: I am a PHD candidate student in the school of public health of Peking University and my major is genetic epidemiology. I am learning the FAM-MDR algorithm, which is used to detect the gene-gene and gene-environment interactions in the data of pedigree. The codes were written by Tom Cattaert of the University of Liege. The algorithms and the sample datasets are available at

Logistic regression to select genes and estimate cutoff point?
Hi, all, I am new to R or even to statistics. Not sure if the question has a answer. But I couldn't find a straight forward answer in the help mailing list. I need use MicroArray data to select several diagnostic genes between Normal samples and Tumor samples and use these genes to predict unknow samples. Since the sample size is so small and data doesn't follow normal distribution, I am

Test de Quade
Hola a todos, Acudo a vosotros después de darle muchas vueltas al tema en Internet y no localizar la solución para algo que creo trivial. Necesito aplicar el test de Quade a un conjunto de datos en el que existe más de una covariable. El ejemplo de dicho test en R es el siguiente: ## Conover (1999, p. 375f): ## Numbers of five brands of a new hand lotion sold in seven stores ## during one week. y

ANCOVA & Post-hoc test
Hello, Despite my search, I didn't find a post-hoc test for an ANCOVA. I used the functions aov() and lm() to run the ANCOVA then I tried TukeyHSD() but it didn't work (because of the covariable is a continuous variable?). Furthermore, I would like to plot the adjusted values (i.e. the values of the tested variable taking into account the covariable). Thanks for your help! N. Poulet

Estimates of coefficient variances and covariances from a multinomial logistic regression?
Hello and thanks in advance for any help, I am using the 'multinom' function from the nnet package to calculate a multinomial logistic regression. I would like to get a matrix estimates of the estimated coefficient variances and covariances. Am I missing some easy way to extract these? Grant [[alternative HTML version deleted]]

Logistic regression with 2 factors and 3 covariates
Hello I'm trying to write a model for my data, but Im not sure it's statistically correct. I have one variable (2 levels: A or B). To explain it, I've got 2 factors and 3 continuous variables. I need to do a logistic regression, but... First: can I actually do a logistic regression with all of this? I know it's a basic question (sorry) but I just cant find a clear answer.
