[R] pls package

Hi All, I am using the cppls function in the pls package, and I want to use cross validation to determine the best number of components. Since Hastie et al recommended a "one standard error rule", i.e., choose the most parsimonious model whose error is no more than one standard error above the

Hummm... stringr depende de stringi, que es el que da el error. Prueba install.packages("stringr", dependencies = TRUE) En principio, R debería instalar todas las dependencias. Pero parece que no es el caso aquí. Un saludo, Carlos J. Gil Bellosta http://www.datanalytics.com El 16 de marzo de

Re: [R] Truncated file upon reading a text file with 0xff characters

Thank you for the answer. I was about to ask why I should avoid text connections, but actually I just noticed that with a binary connection for the read, the problem disappears (I mean, I replace "rt" with "rb" in the file open). R is even clever enough that, when feeded the latin1 file after an

Re: [R] Logistic Regression output baseline (reference) category

The reference category is aliased with the constant term in the default contr.treatment contrasts. See ?contr.treatment , ?C, ?contrasts If you don't know what this means, you should probably consult a local statistical resource or ask about linear model contrasts at a statistical help website

[R] Logistic Regression output baseline (reference) category

Hi, I am trying to use the summary from the glm function as a data source. I am using the call sink() then summary(logisticRegModel)$coefficients then sink(). The independent variables are categorical and thus there is always a baseline value for every category that is omitted from the glm

Re: [R] Truncated file upon reading a text file with 0xff characters

I think you've identified a bug (or more than one) here, but your message is so long, I haven't had time to go through it all. I'd suggest that you write up a shorter version for the bug list. The shorter version would 1. Write the latin1 file using writeBin. 2. Set options(encoding = "")

[R] About calculation of the gravity model in R and STATA software

Dear colleagues! We spent calculation of the gravity model in R and STATA software. For calculations we used the standard package glmm in R (with parameter family = quasipoisson) and ppml in STATA. Call the calculation procedure in R: summary(glmm<-glm(formula=exports ~ ln_GDPimporter +

One technique for dealing with this is called 'multiple imputation'. Google for 'multiple imputation in R' to find R packages that implement it (e.g., the 'mi' package). Bill Dunlap TIBCO Software wdunlap tibco.com On Tue, Mar 15, 2016 at 8:14 AM, Lorenzo Isella wrote:

IMHO this is not a question about R... it is a question about statistics whether R is involved or not. As such, a forum like stats.stackexchange.com would be better suited to address this. FWIW I happen to think that expecting R to solve this for you is unreasonable. -- Sent from my phone.

Dear All, A situation that for sure happens very often: suppose you are in the following situation set.seed(1235) x1 <- seq(30) x2 <- c(rep(NA, 9), rnorm(19)+9, c(NA, NA)) x3 <- c(rnorm(17)-2, rep(NA, 13)) y <- exp(seq(1,5, length=30)) mm<-lm(y~x1+x2+x3) i.e. you try a simple linear
