We introduce simple regression analysis , which explores the relationship between an interval-scale or ratio-scale variable and a second variable of any scale, although more often than not, the second variable i
simple linear regressionOne of the simplest and yet a commonly occurring data analytic problem is exploring the relationship between two numerical variables. In many applications, one of the variables may be regarded as a response variable and the other as a predictor variable and the goal is to...
Instead, we may turn to two alternate methods: the Pearson correlation coefficient and the simple linear regression model. These methods form the basis for the more widely used multiple regression model, which we will discuss in the next chapter....
Correlation and simple linear regression do not provide answers to causality directly. Differences: The regression equation (y=α+βx) can be used to make predictions on Y based on values of X. Correlation usually refers to linear relationships, but it can refer to other forms of dependence su...

Simple Linear Regression Model The following linear regression model is used to describe the relationship between two variables, X and Y: Based on the regression model stated previously, the regression process estimates an equation for a line through a scatter plot of the data that "best" explains...
