Regression analysis examines associative relationships between a
metric dependent variable and one or more independent variables
in the following ways:



• Determine whether the independent variables explain a significant
variation in the dependent variable: whether a relationship exists.



• Determine how much of the variation in the dependent variable can
be explained by the independent variables: strength of the
relationship.

The applications areas are in ‘explaining’ variations in sales of a
product based on advertising expenses, or number of sales people,
or number of sales offices, or on all the above variables.



• Determine the structure or form of the relationship: the
mathematical equation relating the independent and dependent
variables.



• Predict the values of the dependent variable.
