Hi R users, I am using the optim funciton to maximize a log likelihood function. My code is as follows: p<-optim(c(-0.2392925,0.4653128,-0.8332286, 0.0657, -0.0031, -0.00245, 3.366, 0.5885, -0.00008, 0.0786,-0.00292,-0.00081, 3.266, -0.3632, -0.000049, 0.1856, 0.00394, -0.00193, -0.889, 0.5379, -0.000063, 0.213, 0.00338, -0.00026, -0.8912, -0.3023, -0.000056), f,

DeaR all, I am using mob() for model based partitioning, with a dichotomous variable (participant's correct/incorrect response to a test item) regressed onto a continuous predictor related to a given property of the test item. Although this variable is continuous, the value of this variable for many items in this particular analysis is 0. The partitioning criterion is self-reported ability in

Dear useRs: I try to use mob from the party package (thanks Achim and Co.!) to model based recursive partition a data set. The model is a logistic regression specified with model=glinearModel and family=binomial(). Running mob results in a few warnings of the type: In glm.fit ... algorithm did not converge. As I speculate that this may be due to an insufficient number of iterations I am

R Users - Tomorrow night, we are leading a group of R programmers to a site called Stack Overflow, Stackoverflow is a collaborative question and answer site for programmers, currently lacks much R content. to populate some of the most oft-asked and reluctantly-answered questions about R. The R-help mailing list is an indispensable resource to members of the R community. Perhaps owing to its

I try tu use mob() with my data.frame ('data.frame': 288 obs. of 81 variables; factors, numerics and ordered factors) My response is a binary variable and I should use for modelling a logistic regression (family=binomial). I read in the "MOB" Vignette that I could use a formula like this if I would like to have only partitioning variables apart from the response.

Dear all R-users, I wanted to fit a Garch(1,1) model to a dataset by: >garch1 = garch(na.omit(dat)) But I got a warning message while executing, which is: >Warning message: >NaNs produced in: sqrt(pred$e) The garch parameters that I got are: > garch1 Call: garch(x = na.omit(dat)) Coefficient(s): a0 a1 b1 1.212e-04 1.001e+00 1.111e-14 Can any one

Hi, I'm responding to a post about finding roots of a cubic or quartic equation non-iteratively. One obviously could create functions using the explicit algebraic solutions. One post on the subject noted that the square-roots in those solutions also require iteration, and one post claimed iterative solutions are more accurate than the explicit solutions. This post, however, is about

Hi all, this is OT. I've performed a two way anova with repeated mesurements. There's no significant main effect, but the interaction is significannt. Are there any tests in R to examine the interaction?

Friends- I wanted to let people know that there is a new experimental release of this plugin. I would love feedback on syntax and features. There is now a full test suite with fixtures that covers all the available syntax. Look at the test suite for more syntax possibilities. There have been many additions since my last release. Fabien Atelier has been working on this with me and has

The great anticipations are made. The increase is up to 70% last time. (MXXR) is the gainful deal and those who knows it is making money. The drilling achivements of this highly capable oil partnership exceeded all its expectations. Once this fact hits the street there will be no stopping this one. these days it's about 0.022 but we are waiting it to triple. Once the information is made and

Hello, I calculate the correlation between two matrices cor(x,y, method="spearman") and I am wondering if it possible to see only the significant correlations. I can do that for single OTUs with cor.test() command but I would like to have an output for whole matrix. Besides,I would like to plot the relative abundance of each OTU, against the number of significant pair-wise correlations

I need a function like signif(), but returns the rounded values as character strings, formatted with trailing zeros where appropriate. If anyone has one, I would sure appreciate a copy. Thanks -Don Details: signif() rounds a number to a specified number of significant digits, for example: > x <- c(2.503,2.477,0.1204) > signif(x[1],3) [1] 2.5 > signif(x[2],3) [1] 2.48

Dear all, I did a Kruskall-Wallis test for a comparison of a variable of interest between 10 sites and I get a significant result (p=0.0019). however, when I perform a post-hoc test using kruskalmc from the pgirmess package, I get no difference between any of the paired comparisons. I cannot find anything in the internet, not in my stats books about how to explain this contradictory result. I

Dear R users, Using R lme function, I found that both fixed and random effects of variable A on variable B are significant. Now, I'd like to analyze what variables are predicting differences in the slope. In other words, I'd like to know what variables (e.g., variable C) are predicting individual differences in the effects of A on B. I have many data points for A and B for each

The speedups in building RPM's with "mock" from the EPEL packages for RHEL 6 are *profound*, especially if your environment is like mine and you have thousands of user id's. The issue seems to be the handling of "/var/log/lastlog" and similar files, which are otherwise quite large and take significant time to compress and uncompress when laying out new mock

I use tar, but before I start it I do a "getfacl --skip-base -R ." and save the output in a file that is bound to be the first on tape. When I restore such a tarball I do "setfacl --restore=" and all the ACLs are restored in a fell
