Estimation.Zemel.MLE: 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)
