Censored regression models could possibly be used when the dependent variable is just often noticed, and Heckman correction style products may very well be applied once the sample is just not randomly selected through the inhabitants of desire. An alternative to these treatments is linear regression dependant on polychoric correlation (or polyserial correlations) concerning the categorical variables. This kind of procedures vary in the assumptions designed in regards to the distribution of the variables during the population. Should the variable is positive with low values and represents the repetition in the event of the event, then count designs much like the Poisson regression or even the destructive binomial model could possibly be used
