Simple Linear Regression gives us a fuller understanding of the relationship between predictor and response. With a few assumptions regarding the error that surrounds our regression line, we are able to find the best line to describe this relationship, a line directly related to our correlation. ...
the linear regression model is called linear because f(x;β) is linear of the parameters {βi} 3. Parameter estimation 3.1. General procedure: (1) select a measure of fitness (2) optimize the measure with respect to the model parameters for a data set **3.2. Classic methods: ** Least...

In Section 3.2 , we will see that when we use a regression model we implicitly make a series of assumptions. We then consider a series of tools known as regression diagnostics to check each assumption. Having used these tools to diagnose potential problems with the assumptions, we look at ...
Simple Linear Regression Now, for simple linear regression, we compute the slope as follows: To show how the correlation coefficient r factors in, let’s rewrite it as where the first term is equal to r, which we defined earlier; we can now see that we could use the “linear correlation...

So, now you know how to perform a simple linear regression test in R. Performing a linear regression test is super easy, you just use the lm function. I’ve also shown you how to plot a basic scatter plot, along with the regression line. R Studio version used: 1.2.5033R version us...
