    Article 18 April 2019

  2. A New Look at the Models for Ordinal Categorical Data Analysis

  3. Inferences in Binary Dynamic Fixed Models in a Semi-parametric Setup

    In a longitudinal setup, the so-called generalized estimating equations approach was a popular inference technique to obtain efficient regression...

  4. A Parameter Dimension-Split Based Asymptotic Regression Estimation Theory for a Multinomial Panel Data Model

    In this paper we revisit the so-called non-stationary regression models for repeated categorical/multinomial data collected from a large number of...
