It uses the method of least squares to draw a curve that passes close to as many data points as possible. The formula that represents this is quadratic/cubic/quartic regression. @STAT[EXE]48Pack*?( @GUIDEKEYLOG(NOTEQPPPPPPPPPPPPPPPPPP0PPPPPPPPPPPPPPPPPPPP$P$$')xzIt Quadratic regressionx Model formula ... y=ax+bx+c a .... regression second coefficient b .... regression first coefficient c .... regression constant term (y-intercept) r ... coefficient of determination MSe .. mean square error MCubic regression Model formula ... y=ax+bx+cx+d + a .... regression third coefficient b .... regression second coefficient c .... regression first coefficient d .... regression constant term (y-intercept) r.... coefficient of determination MSe .. mean square error MQuartic regression Model formula ... y=ax+bx+cx+dx+e a .... regression fourth coefficient b .... regression third coefficient c .... regression second coefficient d .... regression first coefficient e .... regression constant term (y-intercept) r ... coefficient of determination MSe .. mean square error
