phi: Function phi(t)

In sporm: Semiparametric Proportional Odds Rate Model

Description

A function can be used to calculate the approximate probability masses p1,...,pN of the discretized baseline distribution F.

Usage

phi(N, theta, lambda)

Arguments

N	integer N=m+n, the sum of the two smple sizes
theta	the value of the proportionality parameter θ
lambda	m/N

Details

Returns approximation of probability masses p= phi(N, theta, lambda)/N of the discretized baseline distribution F.
