regression equation

URL copied Share URL
  1. [statistics] The mathematical formula applied to independent variables to predict the dependent variable being modeled. The notation in regression equations is always Y for the dependent variable and X for the independent variables. Each independent variable is associated with a regression coefficient describing the strength and sign of that variable's relationship to the dependent variable. A regression equation might look like this (where b represents a regression coefficient):
    Y = b0 + b1X1 + b2X2 + …bnXn
