Hi everyone, I am having a bit of trouble correctly structuring an
equation in R.
Here is the equation
Here is what I thought
for(i in 1:numItem)for(x in 1:numCat)
Ptheta[,i,x]<-(exp(-1.702*a[i]*(theta-b[i,x+1]))
My problem is that I am not sure how to get it to read the equation as
having two indexing points (i and x). Right now it is trying to read
it as a matrix, but each value (i and x) are only vectors. Does anyone
have any suggestions on how to get R to recognize this? As an example,
numItem may = 20 and numCat may = 3 and I am trying to evaluate this
over all values of numCat for each value of numItem.
Thanks,
Brendan
