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.
DEFINITION of 'Nonlinear Regression'. A form of regression analysis in which data is fit to a model expressed as a mathematical function.Simple linear regression relates two variables (X and Y) with a straight line (y = mx + b), while nonlinear regression must generate a line (typically a curve) as if every value of Y was a random variable.The goal of the model is to make the sum of the squares as small as possible.onlinear regression modeling is similar to linear regression modeling in that both seek to graphically track a particular response from a set of variables.
