Hi,
I need you help to correct the code below please I have this error Error in if (v[j] >= 0) yo[i, j] <- 1 else yo[i, j] <- 0 : missing value where TRUE/FALSE needed library(mvtnorm) #Load mvtnorm package N<-200;P<-9 W=matrix(NA, nrow=N, ncol=2) xi=matrix(NA, nrow=N, ncol=2) Eta=numeric(N) phi<-matrix(data=c(1.0,0.3,0.3,1.0),ncol=2) yo<-matrix(data=NA,nrow=N1,ncol=P); p<-numeric(P); v<- numeric(P) for (t in 1:25) { for (i in 1:N) { xi1[i,]=rmvnorm(1, c(0,0), phi) delta1<-rnorm(1,0,sqrt(0.3)) eps<-rnorm(3,0,1) Eta[i]=0.6*W[i,1]+0.6*W[i,1]*xi[i,1]+0.6*W[i,2]*xi[i,2]+0.6*W[i,2]*xi[i,2]*xi[i,2]+0.6*xi[i,1]+0.6*xi[i,2]+0.6*xi[i,1]*xi[i,1]+delta v[1]<-1.0+xi[i,1]; v1[2]<-1.0+0.8*xi1[i,1]; v1[3]<- 1.0+0.8*xi1[i,1] v[4]<-1.0+xi[i,2]; v1[5]<-1.0+0.8*xi1[i,2]; v1[6]<- 1.0+0.8*xi1[i,2] v[7]<-1.0+Eta[i]+eps[1]; v[8]<-1.0+0.8*Eta[i]+eps[2]; v[9]<-1.0+0.8*Eta[i]+eps[3] for (j in 1:9) { if (v[j]>=0) yo[i,j]<-1 else yo[i,j]<-0 } } }#end Any help would be appreciated.
