A multiple linear regression can thus test the effects of various predictors simultaneously. $\begingroup$ So if in a multiple regression R^2 is .76, then we can say the model explains 76% of the variance in the dependent variable, whereas if r^2 is .86, Multiple R-squared is the R-squared of the model equal to 0.1012, and adjusted R-squared is 0.09898 which is adjusted for number of predictors. In the simple linear regression model R-square is equal to square of the correlation between response and predicted variable. We can run the function cor() to see if this is true.

Steps to apply the multiple linear regression in R Step 1: Collect the data. Step 2: Capture the data in R. Next, you’ll need to capture the above data in R. Realistically speaking, when Step 3: Check for linearity. Before you apply linear regression models, you’ll need to verify that R multiple regression This tutorial shows how to fit a multiple regression model (that is, a linear regression with more than one independent variable) using R. The details of the underlying calculations can be found in our multiple regression tutorial. Multiple Linear Regression.
