…pendent variable has more than two categories, then it is multinomial logistic regression. When the dependent variable category is to be ranked, then it is ordinal logistic regression (OLS). To obtain the maximum likelihood estimation, transform the dependent variable in the logit function. Logit is basically a natural log of the dependent variable and tells whether or not the event will occur. Like OLS, ordinal logistic regression does not a…

Resampling is also known as Bootstrapping or Monte Carlo Estimation. In order to understand the concept of resampling, the researcher should understand the terms Bootstrapping and Monte Carlo estimation: The method of bootstrapping, which is equivalent to the method of resampling…
