https://info.5y1.org/regression-equation-calculator_1_8ddae5.html
Multiple Linear Regression So far, we have seen the concept of simple linear regression where a single predictor variable X was used to model the response variable Y. In many applications, there is more than one factor that inﬂuences the response. Multiple regression models thus describe how a single response variable Y depends linearly on a ...

Calculation of Multiple Regression with Three Independent ...
Multiple regression is used to de velop equations that describe relation ships among several variables. This paper describes a multiple re gression program for an equation with one dependent and three independent variables, which was written for a Hewlett-Packard 97 prograrnable "pocket" calculator. Once each variable is entered, the
