Member Function Documentation

double RazorBack::Linreg_::lin_reg ( const Rmatdbl_ & Xmeas, const Vecdbl_ & Ymeas, const Vecdbl_ & Userwgt )

lin_reg(Xmeas, Ymeas [,Userwgt]): multivariate linear regression calculating the parameters P in the equation Y=P[0]*X[0]+...+P[Np-1]*X[Np-1]. Xmeas is an Nm x Np matrix holding Nm rows of Np independent vars, Ymeas is an Nm-long vector holding the dependent vars. Userwgt is an optional Nm-long vector of weights. Throws Dimexc_ and Toofewexc_. Return value: the residual deviation. Invoke param(), sdev(), correl() for the detailed results.
