When the response variable is a proportion or a binary value 0 or 1 , standard regression techniques must be modified. Both methods yield a prediction equation that is constrained to lie between 0 and 1.

But if more than one independent variable is associated with a dependent variable, then such a regression model is called a multiple regression model. For example sales turnover of a product a dependent variable is associated with more than one independent variables such as price of the product, expenditure on advertisement.
