Declaration
Procedure LogisticFit(B: TVec; X, Y: TVec; Constant: boolean = false; Weights: TVec = nil);
| Parameter | Description |
|---|---|
| X | Vector of independent variable. |
| Y | Vector of dependent variable. |
| Constant | If false, B[0] i.e. constant term in nominator is set to 0.0. |
| Weights | Weights (optional). Weights are used only if they are set. |
| B | Returns regression coefficients for logistic function. |
Description
The routine fits equations to data by minimizing the sum of squared residuals. The observed values obey the following equation:
