void LnFit(TVec *B, TVec *X, TVec *Y, TVec *Weights = null);
Fits simple logarithm equation y(x)=b[0] + b[1]*ln(x) to data.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | B | TVec * | Returns regression coefficients for natural logarithm function. |
| 2 | X | TVec * | Vector of independent variable. |
| 3 | Y | TVec * | Vector of dependent variable. |
| 4 | Weights = null | TVec * | Weights (optional). Weights are used only if they are set. |
Remarks:
The routine fits equations to data by minimizing the sum of squared residuals. The observed values obey the following equation:
