Econometrics: Changing units of measurement
How changing units of variables affect the estimated regression coefficients and other measures
Description
This Econometrics course covers the concept of Scaling - Changing Units of Measurement.
What is this concept of Scaling?
Think of it in this manner:
Let's say you are working with 2 variables - Weight and Height, where, Weight is measured in Kilograms and Height is measured in inches. When you run a regression of Weight on Height, you get the estimated intercept to be -79.24 and the estimated slope to be 4.16.
Now, if you decide to change the unit of Weight from kilograms to pounds or the unit of Height from inches to centimeter, then how will the estimated intercept and slope change?
And that's exactly what you are going to learn in this course!
