Learn how to calculate and interpret regression and hypothesis tests for regression statistics. In addition, Dr. Richard Chua explains how to perform residual analysis to validate the model.
- In your black belt project,…once the correlation is determined to be significant,…the next question is,…what is the exact form of the relationship…or what is the regression equation?…You may ask why the term regression?…It's historical…and the term that can be attributed to…Victorian statistician, Sir Francis Galton.…Who first used it to express how…as more and more data is collected…their values tend to get closer…or regress toward the mean.…And those means represent the line of best fit.…
Which is termed the regression equation.…More specifically, what is the Y equals F of X.…Once that is known, axis can be controlled,…to achieve the desired level of Y.…For instance is there any relationship…between the speed of a car…and the stopping distance when brakes are applied?…Let's use Minitab to learn some examples on regression.…To get started go up to your exercise files…and download regression data dot M T W.…
And open that file.…Here we have in column one, speed…and in column three, stopping distance.…Of interest to us is whether…
