Beta response models

Description

Generating beta response models. Implemented to compare the hierarchical logistic regression models with beta response models.

Usage

 betaresp(x, p1, p2, alpha, gamma, hi)

Arguments

x	Gradient values
p1, p2	response endpoints
alpha, gamma	shape parameters of the response
hi	maximum height of response
