i try to generate 27*5 matrix of observation using the following code but is
given error
kindly assist and correct the problem
x1<-c(-1,0,1,-1,0,1,-1,0,1,-1,0,1,-1,0,1,-1,0,1,-1,0,1,-1,0,1,-1,0,1)
x2<-c(-1,-1,-1,0,0,0,1,1,1,-1,-1,-1,0,0,0,1,1,1,-1,-1,-1,0,0,0,1,1,1)
x3<-c(-1,-1,-1,-1,-1,-1,-1,-1,-1,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,1,1)
mu<-50+5*(x1^2+x2^2+x3^2)
sig<-100+5*((x1-0.5)^2+x2^2+x3^2)
x.matrix<-matrix(0,nrow=27,ncol=5)
for(i in 1:27){
x.matrix[i,j]<-rnorm(5,mu[i],sig[i])
}
Thanks
