Alternative Estimators in Logit Model in The Presence of Multicollinearity and Heteroscedasticity with A Stochastic Linear Restricted

Saja Mohammad Hussein


We propose grafting the maximum likelihood estimator (ML)for logit model into the mixed estimator (ME) and stochastic restricted ridge regression estimator (SRRR) for a linear model. To obtain estimators that can apply to models in which the dependent variable is binary in the presence of multicollinearity problem in the case of the heteroscedasticity of error term when stochastic linear restrictions are assumed to hold. A mean square error (MSE) is used to compare the performance of the proposed estimators through a simulation study and investigate The behavior of these estimators using some Ridge parameters.

Regarding indexing issue:

We have provided the online access of all issues & papers to the all  indexing agencies (as given on our journal home web site). It’s depend on indexing agencies when, how and what manner they can index or not. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information.
