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...

Simple linear regression is used to model the relationship between two continuous variables. Often, the objective is to predict the value of an output variable based on the value of an input variable.

Consider the linear regression model Y= X 1+±+ (X), where X and are independent random variables, has a mean of zero and variance 2, and is some unknown function used to model heteroscedasticity. Many methods have been proposed for testing H 0: (X) 1, the hypothesis that the error ...
