Hi,
I have problem with my R program. Actually, it just a simple program, but I do
not know the error is. Here is part of my program:
....
if (tau2ca==0) {MVvc <- 0.01} else {MVvc <- tau2ca}
ri_vc <- si2/MVvc
vi_vc <- ri_vc + 1
Y_bar_vc <- sum(y/vi_vc)/sum((1/vi_vc))
tau2MVvc <- sum((1/vi_vc)*(y - Y_bar_vc)^2)/(k-1)
....
But then, there is an error displayed in workspace
Error in if (tau2ca == 0) { : missing value where TRUE/...
