Nawata [8–10] proposed a new estimator for the standard regression, censored regression, and binary choice models, based on grouping of observations. This paper shows that Nawata's grouping method can be generalised to various types of estimation problems and represents a new class of...

The female labor supply models have been widely used in labor economics. The models are usually estimated by Heckman’s two-step estimator. However, Heckman’s two-step estimator often performs poorly. This paper considers an estimation of the models by the maximum likelihood method. An...

Process capability analysis has been widely applied in the field of quality control to monitor the performance of industrial processes. In practice, lifetime performance index CL is a popular means to assess the performance and potential of their processes, where L is the lower specification...

Let Z(τ,t) is the number of individuals at time τ having more than θ(t−τ) descendants at time t,tτ. Here θ(t) is some non-negative function. Limit distributions for Z(τ,t) when population evolves according to critical branching processes with time homogeneous immigration and...

This paper examines the … GARCH model under various non-normal error distributions in order to evaluate skewness and leptokurtosis. The empirical … estimated under normality, in terms of: (i) capturing skewness and leptokurtosis; (ii) the maximized log-likelihood values; and …
