Next, if we say X=In x, Y=In y, and A=In a, the formula corresponds to linear regression formula Y=A+bX. n@STAT[EXE] 8Pack*?( @GUIDEKEYLOG(NOTEQPPPPPPPPPPPP0PPPPPPPPPPPPPP$$$)')xzNexThe following is the power regression model formula. + y=axb a .... regression coefficient b .... regression power r .... correlation coefficient r ... coefficient of determination MSe .. mean square error
