Estimation.RUM.MultiType.MLE {StatRank} | R Documentation |
Performs parameter estimation for a Multitype Random Utility Model
Description
This function supports RUMs 1) Normal 2) Normal with fixed variance (fixed at 1) 3) Exponential
Usage
Estimation.RUM.MultiType.MLE(Data, K = 2, iter = 10, dist, ratio = 0.2,
race = FALSE)
Arguments
Data |
data in either partial or full rankings |
K |
number of components in mixture distribution |
iter |
number of EM iterations to run |
dist |
underlying distribution. Can be "norm", "norm.fixedvariance", "exp" |
ratio |
parameter in the algorithm that controls the difference of the starting points, the bigger the ratio the more the distance |
race |
TRUE if data is sub partial, FALSE (default) if not |
Value
results from the inference
Examples
Data.Tiny <- matrix(c(1, 2, 3, 3, 2, 1, 1, 2, 3), ncol = 3, byrow = TRUE)
Estimation.RUM.MultiType.MLE(Data.Tiny, K=2, iter = 3, dist= "norm.fixedvariance")
