emplik (version 1.3-2)

emplik-package: Empirical likelihood for mean functional/hazard functional with possibly censored data.

Description

Empirical likelihood ratio tests and confidence intervals for means/hazards from possibly censored and/or truncated data. In particular, empirical likelihood for the Kaplan-Meier/Nelson-Aalen estimators. Now does AFT regression too.

Details

For non-censored data and mean parameters, use el.test( ).

For censored data and mean parameters, use el.cen.EM2( ).

For censored data and hazard parameters, use emplikH1.test( ) [Poisson type likelihood]; use emplikH.disc( ) [binomial type likelihood].

For constructing confidence intervals from likelihood ratio, use findUL( ).
