Scalar Explanatory Linear Regression Calculator & Formulas
Simple Linear Regression Calculator
An online statistical linear regression definition and calculator based on scalar & explanatory variables.
- Regression Equation Y = a + bx
- Slope b = (NΣXY - (ΣX)(ΣY)) / (NΣX2 - (ΣX)2)
- Intercept a = (ΣY - b(ΣX)) / N
- a = The intercept point of the regression line and the y axis
- b = The slope of the regression line
- X and Y are the variables
- N = Number of values or elements
