Linear RegressionIn statistics, linear regression is a method of estimating the conditional expected value of one variable y given the values of some other variable or variables x.
Regression, in general, is the problem of estimating a conditional expected value.
The Linear Regression study analyses the data on-screen (not any data off screen) and, by the method of least squares, plots the straight line that best fits the visible data with the formula
- where Sx is the sum of X at each position, Sxy is the sum of X Y at each position, and so forth.
