Example #1 – Collecting and capturing the data in Rįor this example, we have used inbuilt data in R. This model seeks to predict the market potential with the help of the rate index and income level. In this section, we will be using a freeny database available within R studio to understand the relationship between a predictor model with more than two variables. Essentially, one can just keep adding another variable to the formula statement until they’re all accounted for. The lm() method can be used when constructing a prototype with more than two predictors. and x1, x2, and xn are predictor variables.Įxamples of Multiple Linear Regression in R.Where Y represents the response variable.Now let’s see the general mathematical equation for multiple linear regression A child’s height can rely on the mother’s height, father’s height, diet, and environmental factors. Now let’s look at the real-time examples where multiple regression model fits.įor example, a house’s selling price will depend on the location’s desirability, the number of bedrooms, the number of bathrooms, year of construction, and a number of other factors. Such models are commonly referred to as multivariate regression models. There are also models of regression, with two or more variables of response. The formula represents the relationship between response and predictor variables and data represents the vector on which the formulae are being applied.įor models with two or more predictors and the single response variable, we reserve the term multiple regression. This function is used to establish the relationship between predictor and response variables. Lm() function is a basic function used in the syntax of multiple regression.
