ELYP (version 0.7-5)

ELrange: Find the Ractangular parameter region where EL is Only 4 below the Maximum Value.

Description

This function compute the hazard ratio, given beta1 beta2 a X and Mulam = int g(t) dH(t).

Usage

ELrange(mle, loglik, step, DataMat)

Value

A list with Step [a vector] and TempV [a matrix]

Arguments

mle

The NPMLE of the parameters value.

loglik

a function. Takes 2 inputs: mle and DataMat. output one scalar = loglik value.

step

a vector, same length as mle. The initial search step.

DataMat

The data matrix, to be used by loglik( ).

Examples

## censored regression with one right censored observation.
## we check the estimation equation, with the MLE inside myfun7. 
y <- c(3, 5.3, 6.4, 9.1, 14.1, 15.4, 18.1, 15.3, 14, 5.8, 7.3, 14.4)
x <- c(1, 1.5, 2,   3,   4,    5,    6,    5,    4,  1,   2,   4.5)
