Test for Heteroscedasticity, Multicollinearity and Autocorrelation

In the articles earlier, we understood the importance of observing the three behaviors in the model: Homoscedasticity, Multicollinearity and Autocorrelation. We would be going over the concept and R application of most used tests in multiple regression modeling. The list is as follows: Breush-Pagan test VIF (Variance Inflation Factor) Runs…

Multiple Linear Regression

In the last two articles, we explored the concept of Simple Linear Regression Model (i.e., regression involving two variables). Although, the practical situations demand much more complexity, for almost all the situations when we apply this concept in real life, we have numerous variables (which might or might not affect…

Testing for Normality

In my previous article, we went over the single variable hypothesis testing. Likewise, we can apply the tests for the double variable testing like, testing for the significance of the difference of means, testing for the difference of population variances and others. But now, we would move over the topic…

Test Statistics for Hypothesis Testing in Statistics with Functions in R Programming

In my previous article, we talked about the terminology in the statistical world of hypothesis testing. Moving on, once we have our hypothesis about the population parameters (based on the sample) in place, we need some sophisticated ways to practically support one claim (either H0 or H1) by using statistical…
