Linear Regression is a supervised modeling technique for continuous data that Note: R-squared value tends to increase as more variables are included in the  Prof. Alexandra Chouldechova. Linear regression. First step: some plotting and summary statistics; Constructing a regression model. Exploring the lm object  The lm() function creates a linear regression model in R. This function takes an R formula Y ~ X where Y is the outcome variable and X is the predictor variable. R is used by professionals in the Data Analysis and Data Science fields as part of their daily work. Use linear regression to model the Time Series data with linear indices (Ex: 1, 2, .. n). The resulting model’s residuals is a representation of the time series devoid of the trend. A linear regression model’s R Squared value describes the proportion of variance explained by the model. A value of 1 means that all of the variance in the data is explained by the model, and the model fits the data well.

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. Predicting Blood pressure using Age by Regression in R. Now we are taking a dataset of Blood pressure and Age and with the help of the data train a linear regression model in R which will be able to predict blood pressure at ages that are not present in our dataset.
