Regression analysis involves
finding the line of best fit through a series
of points. The calculation to find
the line of best fit uses the least
squares method and the outcome
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
outputs multivariate
analysis is used. Strictly
speaking multiple linear regression is a
form of multivariate analysis although not
usually referred to as such.
