Simulate theta values
simTheta
is a function for generating a theta matrix based on the given sample size, mean, standard deviation, and correlation matrix.
simTheta(N, mean_v, sd_v, cor_v)
N
: the number of examinees.mean_v
: a vector containing the mean of each dimension.sd_v
: a vector containing the standard deviation of each dimension.cor_v
: a correlation matrix.a theta matrix.
simTheta
calls mvrnorm
internally.
o <- simTheta( N = 100, mean_v = c(0, 0, 0), sd_v = c(1, 1, 1), cor_v = diag(1, 3) )
