In statistics, simple linear regression (SLR) is a linear regression model with a single explanatory variable.
Learn what linear regression is, how it estimates the linear relationship between a scalar response and one or more explanatory variables, and how it is formulated using matrix notation. See examples, applications, and variations of linear regression models.
9 wrz 2024 · Linear Regression Formula. Formula used for linear regressions is, y = a + bx. Intercept value, a, and slope of the line, b, are evaluated using the formulas given below: [Tex]\begin{array}{l}\large a~=~\frac{\sum y \sum x^{2} ~–~ \sum x \sum xy} {n(\sum x^{2}) ~–~ (\sum x)^{2}}\end{array} \\[/Tex]
