hazreg

grstree

generates a survival tree

grstreearrow

auxiliary quantlet for grstree - generates the arrows in the survival tree

grstreebox

auxiliary quantlet for grstree - generates the boxes in the survival tree

grstreecircle

an auxiliary quantlet for grstree - generates the circles in the survival tree

harefit

non-proportional hazards regression using linear splines. Its results are to be interpreted by haresummary and hareplot.

haresummary

summarizes the output of harefit (non-proportional hazards regression).

hazbase

calculates the baseline hazard and survival function, using the maximum likelihood estimate of the regression parameter beta obatined through hazbeta.

hazbeta

calculates the maximum likelihood estimate of the regression parameter beta in the Cox Proportional hazard model, by Newton-Raphson method.

hazcoxb

calculates the baseline hazard and survival function, using the maximum likelihood estimate of the regression parameter beta obatined through hazbeta.

hazdat

sorts the right-censored data of n individuals to prepare it for hazard regression analysis. The observed data are n triples (t_i,delta_i,z_i): t_i denotes the observed survival time of the i-th individual, delta_i is the censoring indicator, z_i denotes the p-dimensional covariate vector associate

hazkpm

estimates the survival function at the sorted observations of a right-censored data together with the Greenwood pointwise confidence intervals.

haznar

calculates the size of the risk set at each point of the censored survival time data.

hazregll

calculates derivatives up to order 2 of the log-likelihood function at parameter value beta

hazregmain

loads the quantlibs needed by the quantlets in the hazreg quantlib

hazregtest

Tests the quantlets of the hazreg library.

hazrisk

determines which observations are at risk at the time point t_i.

hazsurv

calculates the conditional survival function, using the maximum likelihood estimate of the regression parameter beta obatined through hazbeta.

haztest

calculates the value of the test statistic, the degree of freedom, and the P-value for the likelihood ratio test, Wald's test and the score test for Cox's Proportional Hazards model.

plothare

plots a hare density, distribution function, hazard function or survival function for a model estimated by harefit.

steps4plot

produces a matrix of points for plotting a left continuous step function.

stree

constructs and plots a survival tree - a nonparametric regression model for censored survival data

streeoutput

an auxiliary quantlet for stree, provides the text output and prepares output variables

xhare

Auxiliary quantlet for harefit and plot hare. Computes density, cumulative probability, hazard rates, quantiles, and random sample from a model fitter with harefit.
