Multi-scale analysis of rural and urban areas: A case study of Indian districts
Abhik Ghosh, Souvik Chattopadhay, Banasri Basu
This paper explores the extension of the idea of allometric urban scaling law to study the scaling behaviour of Indian districts, with both the urban and rural population. To proce…
Robust and Efficient Estimation in Ordinal Response Models using the Density Power Divergence
Arijit Pyne, Subhrajyoty Roy, Abhik Ghosh +1
In real life, we frequently come across data sets that involve some independent explanatory variable(s) generating a set of ordinal responses. These ordinal responses may correspon…
Exponential Consistency of M-estimators in Generalized Linear Mixed Models
Andrea M. Bratsberg, Magne Thoresen, Abhik Ghosh
Generalized linear mixed models are powerful tools for analyzing clustered data, where the unknown parameters are classically (and most commonly) estimated by the maximum likelihoo…
Existence and Consistency of the Maximum Pseudo \b{eta}-Likelihood Estimators for Multivariate Normal Mixture Models
Soumya Chakraborty, Ayanendranath Basu, Abhik Ghosh
Robust estimation under multivariate normal (MVN) mixture model is always a computational challenge. A recently proposed maximum pseudo \b{eta}-likelihood estimator aims to estimat…
