How to fit a Linear Regression Model in R, Produce Summaries and ANOVA table for it.

◼︎ What to Expect in this R video Tutorial:

► learn when to use a regression model, and how to use the “lm” function in R to fit a linear regression model for your data

► learn to produce summaries for your regression model using “summary” function in R statistics software; these summaries can include intercept, test statistic, p value, and estimates of the slope for your linear regression model

► become familiar with the Residual Error: a measure of the variation of observations in regression line

► learn to ask R programming software for the attributes of the simple linear regression model using “attributes” function, extract certain attributes from the regression model using the dollar sign ($), add a regression line to a plot in R using “abline” function and change the color or width of the regression line.

► this R tutorial will also show you how to get the simple linear regression model’s coefficient using the “coef” function or produce confidence intervals for the regression model using “confint” functions; moreover, you will learn to change the level of confidence using the “level” argument within the “confint” function.

►You will also learn to produce the ANOVA table for the linear regression model using the “anova” function, explore the relationship between ANOVA table and the f-test of the regression summary, and explore the relationship between the residual standard error of the linear regression summary and the square root of the mean squared error or mean squared residual from the ANOVA table.
