Is neglected heterogeneity really an issue in binary and fractional regression models? A simulation exercise for logit, probit and loglog models

Ramalho, Esmeralda A.; Ramalho, Joaquim J. S. - Centro de Estudos e Formação Avançada em Gestão e … - 2009

In this paper we examine theoretically and by simulation whether or not unobserved heterogeneity independent of the included regressors is really an issue in logit, probit and loglog models with both binary and fractional data. We found that unobserved heterogeneity: (i) produces an attenuation...
