A Simple Linear Regression

Preliminaries Linear Algebra(the concepts of space, vector) Calculus An Introduction to Linear Regression Notations of Linear Regression1 We have already created a simple linear model in the post “An Introduction to Linear Regression”. According to the definition of linearity, we can develop the simplest linear regression model:
[ Ysim w_1X+w_0tag{1} ]
where the symbol (sim) is read as “is approximately modeled as”. Equation (1) can also be described as “regressing (Y) on (X)(or (Y) onto (X))”.
