Create a matrix with increment and element with zero subscript
Hello,
Does anyone knows how to deal with zero subscript in R. I have this code:
for (i in 1:nitems){
+ for (j in 1:ncat-1) {
+ draw<-matrix(rnorm(nitems*(ncat-1),seed1,seed2),nitems,(ncat-1))
+ d<-( sigma_d*draw ) + mu_d
+ draw<-matrix(rtnorm((nitems*(ncat-1)),mean = seed1, sd = seed2, lower = .1, upper = 1.5),nitems,(ncat-1))
+

set seed for random draws
Hello, all!
I need help on these two problems:
1) If I want to randomly draw numbers from standard normal (or other distributions) in loops e.g.:
ty=0; ks=0
for (i in 1:5) {
set.seed(14537+i)
k<-rnorm(1)
ks[i]<-.3*k+.9
if (ty==0) {
while ((ks<.2)||(ks>3)) {
#set.seed(13237+i*100)
k<-rnorm(1)
