RegModels::LogisticFit Function

void LogisticFit(TVec B, TVec X, TVec Y, bool Constant = false, TVec Weights = null);

Fits logistic equation to data.

#	Name	Type	Description
1	B	TVec *	Returns regression coefficients for logistic function.
2	X	TVec *	Vector of independent variable.
3	Y	TVec *	Vector of dependent variable.
4	Constant = false	bool	If false, B[0] i.e. constant term in nominator is set to 0.0.
5	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:

Y = b[0] + \cfrac{b[1]-b[0]}{1+\exp (-b[2]\cdot x + b[3] )}
