Each week, we select a recently published Open Access article to feature. This week’s article comes from Statistica Neerlandica and proposes a methodology for eliminating nuisance parameters.
The article’s abstract is given below, with the full article available to read here.
2023). Inference in the presence of likelihood monotonicity for proportional hazards regression. Statistica Neerlandica, 1– 18. https://doi.org/10.1111/stan.12287, & (
Proportional hazards are often used to model event time data subject to censoring. Samples involving discrete covariates with strong effects can lead to infinite maximum partial likelihood estimates. A methodology is presented for eliminating nuisance parameters estimated at infinity using approximate conditional inference. Of primary interest is testing in cases in which the parameter of primary interest has a finite estimate, but in which other parameters are estimated at infinity.More Details
