Hello useRs, MBESS (Methods for the Behavioral, Educational, and Social Sciences) has recently been released and should be on all of the mirrors by now (with binaries for Mac and Windows: http://cran.r-project.org/src/contrib/Descriptions/MBESS.html).

Hi everyone,I would like to test a mediation model, that has several control variables. More specifically, I would like to test the indirect effect with bootstrapping. However, all the packages I have found so far (e.g. MBESS) only allow testing a simple mediation model (One independent, one mediator, one dependent) so that I cannot include any controls. Can somebody help me? [[alternative HTML version deleted]]

Dear R fans ( and wiki fans), I am just writing a draft to introduce confidence intervals of various "effect sizes" to my students. Surely, I'll recommend the package MBESS in R. Currently, it means I have to recommend R's interface at first. As a statistics teacher in a dept of psychology, I often have to reply why not to teach SPSS. Psychologists and their students hate to memorize codes, or even to call any function with a list of parameters. I know if I have a...

Hi everyone, I use the boot package within the MBESS package to automate much of the hard part for folks interested in performing a (simple) mediation model. The function mediation() works well, except for a (probably) unrealistic artificial data set. When I apply the bootstrap I sometimes get: Error in t.star[r, ] <- res[[r]] which is (I think)...

...on an earlier article by Cureton, who in turn cited an American Journal of Psychology article by Holtxman(1950, v63, 615-617). http://amstat.tandfonline.com/doi/abs/10.1080/00031305.1968.10480435?src=recsys Searching on that article I see the first hit is a citation to some R documentation for hte MBESS::s.u function, which does implement it as recommended by Holtzman. If I were voting on this I would put greater weight on the JK&M but that's just because it is incredibly likely that I could do the math. Best; David. > > -pd > > >> >> Thanks, Peter. &...

Hello, I want to know if there are some functions or packages to solve differential and integral equation using R. Thanks. Shao chunxuan. [[alternative HTML version deleted]]

Dear, We are trying to determine the (one-sided) CI for the coefficient of variation in a small sample (say n = 10), with mean 100 and standard deviation 21. It appears though that the R-function ci.cv() and our simulation do not agree. The R-code: library(MBESS) n = 10 ci.cv(mean = 100, sd = 21, n = 10, conf.level = 0.9) U10.95 <- 0.3551754 ci.cv(mean = 100, sd = 21, n = 10, conf.level = 0.6) U10.80 <- 0.2742255 cv.x <- c() m10.95 <- c() m10.80 <- c() for(j in 1:10){ for(i in 1:10000){ X <- rnorm(n, 100, 21) cv.x[i] <- sd(X)/m...

we have some initial data from our field sampling. From the means and variances, we see your sampling field is much heterogeneous (not uniform). We are looking for a "R" program for sampling size determination. Right now, we are not good enough to write a whole "R" program, so please help. [[alternative HTML version deleted]]

...The second question I have is in regards to using RApply to call R functions which rely on functions in other libraries. I've resorted to creating a function in my excel file which looks something like... Cell Function A1 getLibs<-function(){ A2 library(MBESS) A3 library(corpcor) A4 } B1 =rproc(A1:A4) C1 =rApply("getLibs") Is their a better way to go about accomplishing this? Thanks in advance for any insights you have either of these quesitons Ben ___________________________________...

I'm trying to convert an S-Plus program to R.  Since I'm a SAS programmer I'm not facile is either S-Plus or R, so I need some help.  All I did was convert the underscores in S-Plus to the assignment operator <-.  Here are the first few lines of the S-Plus file:   sshc _ function(rc, nc, d, method, alpha=0.05, power=0.8,              tol=0.01, tol1=.0001, tol2=.005, cc=c(.1,2),
