Prediction of Heart Disease using Multiple Linear. Multiple linear regression in R Dependent variable: Continuous independent variable in the regression model. The model is: Birthweight (y) = -7.165 + 0.313 * (Gestation) – 0.665*(Smoker) + 0.02*(mppwt) For gestation, there is a 0.313 lb increase in birthweight for each extra week of gestation. For each extra pound (lb) a mother weighs, the baby’s weight increases by 0.02 lbs. A binary, Multiple linear regression attempts to model the relationship between two or more explanatory variables and a response variable by fitting a linear equation to observed data.

Multiple Linear Regression and the General Linear Model

Predicting share price by using Multiple Linear Regression. The model says that Y is a linear function of the predictors, plus statistical noise. Simple regression: Y i = β 0 + β 1 x i + ε i Multiple regression: Y i = β 0 + β 1 …, Rather than having a simple linear model of the form Y = 0 + 1X, you could add more predictors. Perhaps a polynomial of the form Y = 0 + 1X + 2X2 would be a better t. Along similar lines, you may be able to transform one of the variables to convert the model into a linear model. Either way (adding predictors or transforming existing predictors) we have an exciting challenge in regression.
