BloombergLP::bdlsta::LineFit::fitIfValid

Calculate line fit coefficients when data is sufficient.

Synopsis

Declared in <bdlsta_linefit.h>

int
fitIfValid(
    double* alpha,
    double* beta) const;

Description

Calculate line fit coefficients Y = Alpha + Beta * X, and populate the specified alpha (intercept) and beta (slope). Return 0 on success, and non‐zero otherwise. The computations is unsuccessful if 2 > count or all X's are identical.

Return Value

0 on success, and a non‐zero value otherwise

Parameters

Name

Description

alpha

receives the intercept of the fitted line

beta

receives the slope of the fitted line
