## The formula of Sxx, Syy and Sxy in linear regression

In linear regression, the formulas for Sxx, Syy and Sxy for data set in statistics

**Sum of squares of the dependent variable (Syy):**

Syy = Σ(y – ȳ)²

**Sum of squares of the independent variable (Sxx):**

Sxx = Σ(x – x̄)²

**Sum of cross-products (Sxy):**

Sxy = Σ(x – x̄)(y – ȳ)

where:

- Σ denotes the sum of all data points.
- x represents the observed values of the independent variable.
- y represents the observed values of the dependent variable.
- x̄ is the mean (average) of the independent variable.
- ȳ is the mean (average) of the dependent variable.
