Linear Regression in R If you do not know the above-listed regression topics, you must learn these techniques; surely, it will boost your knowledge about regression. We’ve also discussed regression examples using well-known datasets and then applied them in the R language in the above-referred topics. Summary: R linear regression uses the lm() function to create a regression model given some formula, in the form of Y~X+X2. To look at the model, you use the summary() function. This whole concept can be termed as a linear regression, which is basically of two types: simple and multiple linear regression. R is one of the most important languages in terms of data science and analytics, and so is the multiple linear regression in R holds value. Fitting a linear regression model.
