Linear Regression in R (R Tutorial 5.1) MarinStatsLectures [Contents] Multiple Linear Regression. Model Specification and Output. In reality, most regression analyses use more than a single predictor. Specification of a multiple regression analysis is done by setting up a model formula with plus (+) between the predictors:

First, import the library readxl to read Microsoft Excel files, it can be any kind of format, as long R can read it. To know more about importing data to R, you can take this DataCamp course.

Residuals are the differences between the prediction and the actual results and you need to analyze these differences to find ways to improve your regression model.

Part III | Regression tips: learnings from an engineer; Part IV | 7 copy & paste steps to run a linear regression analysis using R; Part V | Next steps: Improving your model; Part I | My scope of knowledge upon beginning to write this post. First, to establish grounds, let me tell you what I do know about regression, and what I can do in R. Ordinary least squares Linear Regression. LinearRegression fits a linear model with coefficients w = (w1, …, wp) to minimize the residual sum of squares between the observed targets in the dataset, and the targets predicted by the linear approximation.
