In this paper, we develop a modified maximum likelihood (MML) estimator for the multiple linear regression model with underlying student t distribution. We obtain the closed form of the estimators, derive the asymptotic properties, and demonstrate that the MML estimator is more appropriate for...

We can to analyse the dynamic of the average level for the social productivity of the work in Romania, by means of the statistical methods with view of the factorial influences on the base of indexes numbers.
