MULTIPLE REGRESSION measures the effect a group of survey questions (called the independent variables) has on a single survey question (or an average of a group of questions), called the dependent variable.
In statistics, linear regression is an approach for modeling the relationship between a scalar dependent variable y and one or more explanatory variables (or independent variables) denoted X. The case of one explanatory variable is called simple linear regression.inear regression can be used to estimate the values of Î² 1 and Î² 2 from the measured data. This model is non-linear in the time variable, but it is linear in the parameters Î² 1 and Î² 2; if we take regressors x i = (x i1, x i2) = (t i, t i 2), the model takes on the standard form.
