Dear R fans,
MASS::mvrnorm with empirical=T is very useful to reproduce practice
data of published papers. Now I want to reproduce a binomial variable
with multiple normal variables. The target paper gave a big corr table
with sd(s) and Means including a GENDER variable. Is there a
point-biserial
search could be
recursive.
I am writing sem sample codes for a popular Chinese SEM textbook. Hope sem
package can be more powerful :)

I checked through every 3 factor * 3 loading case.
While, 4 factor * 3 loading failed.
the data is 6 factor * 3 loading

Dear R fans,
I am preparing a lecture discussing the paper of Wilkinson and APA
Task Force on Statistical Inference (1999, American Psychologist, 54,
594-604.) I'd like to demo their Figure 3B (p. 602) with R. That is to
add plotMeans(...) with dots of BHH2::dotPlot(...) . Is there any
elegant scr
I think you should try one X for A/X=sum(exp(c_i/d -log(X)))
The optional X could be as the following ...
## to test ### C = c(c_i/d; i=1,2,...,n)
n<-1000;
C<-runif(n,700,1000);
#
M<-1;while (2*M < Inf) M<-2*M;
X<- exp(max(C) - log (M/n));
cat('A=',sum(exp(C-log(X))),'*',X)
I should have read the following page on R_Extension_for_MediaWiki
http://mars.wiwi.hu-berlin.de/mediawiki/sk/index.php/R_Extension_for_MediaWiki_v0.06#New_tags_and_attributes
Has anybody seen an ... online example page in English?
I really wish wiki.r-project.org be equipped with parameter input
