Estimation.Zemel.MLE {StatRank}R Documentation

Estimates Zemel Parameters via Gradient Descent

Description

This function takes in data broken into pairs, and estimates the parameters of the Zemel mode via Gradient Descent

Usage

Estimation.Zemel.MLE(Data.pairs, m, threshold = 1e-04,
  learning.rate = 1/30000)

Arguments

Data.pairs

data broken up into pairwise comparisons

m

how many alternatives

threshold

turning parameter for gradient descent

learning.rate

turning parameter for gradient descent

Value

a set of scores for the alternatives, normalized such that the sum of the log scores is 0 scores <- Generate.Zemel.Parameters(10)$Score pairs <- Generate.Zemel.Ranks.Pairs(scores, 10, 10) Estimation.Zemel.MLE(pairs, 10, threshold = .1)
