The First Step You Can Take to Understand Regression Analysis
Better than lectures, simple images to understand Regression Analysis. If you are studying Mathematics or Statistics at the High School or College level, you will find this useful.
You will learn what is Regression and the 2 lines of regression.
There are 2 coefficients of Regression , namely the regression coefficient of y on x and the regression coefficient of x on y. The formulas of each is given here.
Coefficients of Regression
You will be introduced to the 2 lines of regression, namely the regression line of y on x, where y is the dependent variable and the regression line of x on y where x is the dependent variable.
You will learn the relation between the regression
coefficients , standard deviation and correlation coefficient
Basically, all the formulas that you need for problem solving are provided in these posts.
