We develop inference tools in a semiparametric partially linear regression model with missing response data. A class of estimators is defined that includes as special cases a semiparametric regression ...

Harnessing a pervasive type of cellular messenger shows early experimental promise as a routine way of sampling and monitoring the body’s response to prescription drug exposure. Purdue University-led ...

A new functional form of the response probability for a qualitative response model is proposed. The new model is flexible enough to avoid the constraint of independence from irrelevant alternatives, ...
