Sorted by: 19. S x x is the sum of the squares of the difference between each x and the mean x value. S x y is sum of the product of the difference between x its means and the difference between y and its mean. So S x x = Σ ( x − x ¯) ( x − x ¯) and S x y = Σ ( x − x ¯) ( y − y ¯). Both of these are often rearranged ...

Part 4: Simple Linear Regression Implementation From … In statistics, linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables (also known as dependent and independent variables). The case of one explanatory variable is called simple linear regression; for more than one, the process is called multiple linear regression. This term is distinct from multivariate linear regression, where multiple correlated dependent variables are predicted, rather than a single sca…
