fit(
double* alpha,
double* beta) const;Calculate line fit coefficients Y = Alpha + Beta * X, and populate the specified alpha (intercept) and beta (slope). The behavior is undefined if 2 > count or all X's are identical.
| Name | Description |
|---|---|
| alpha | receives the intercept of the fitted line |
| beta | receives the slope of the fitted line |
