When I try to create a Rasch simulation of data using the sim.rasch
function, I get more items than I intend
#My code
library(eRm)
#Number of items
k <- 20
#Number of participants
n <- 100
#Create Rasch Data
#sim.rasch(persons, items, seed = NULL, cutpoint = "randomized")
r.simulation <- sim.rasch(n,k)
I end up with 20 participants and 100 items, but the instructions say
otherwise (and I believe I have the most up to date). I reverse the n and
k
sim.rasch(k,n); it works out to how I intended; 100 participants and 20
items.
Can someone explain to me what I'm missing? I've read the package
instructions and didn't see myself missing something (inputting vectors
instead of an integer).
