| Regression analysis involves
finding the line of best fit through a series
of points. The calculation to find

is a regression
equation.
Regression analysis should always be carried
out in conjunction with correlation analysis
to find the goodness of fit.
Types of regression analysis include:
Note that if there are several inputs and/or
