Opis funkcji prognozuj\u0105cej w Excelu i Arkuszach Google<\/h2>\n

Funkcja REGLINX.LINIOWA, znana w wersji angloj\u0119zycznej jako FORECAST.LINEAR, s\u0142u\u017cy do przewidywania warto\u015bci y na podstawie linii trendu (regresji liniowej) wyznaczonej z dost\u0119pnych danych. Jest to nieocenione narz\u0119dzie w analizie danych, kt\u00f3re pozwala na prognozowanie przysz\u0142ych warto\u015bci na podstawie dost\u0119pnych danych historycznych.<\/p>\n

Syntaktyka funkcji i przyk\u0142ady<\/h2>\n

Syntaktyka funkcji REGLINX.LINIOWA w Excelu i Arkuszach Google jest nast\u0119puj\u0105ca:<\/p>\n

=REGLINX.LINIOWA(x, znane_y, znane_x, [const])<\/code><\/pre>\n
    \n
  • x<\/strong> \u2014 warto\u015b\u0107 x, dla kt\u00f3rej prognozowana jest warto\u015b\u0107 y.<\/li>\n
  • znane_y<\/strong> \u2014 zbi\u00f3r danych znanych warto\u015bci y.<\/li>\n
  • znane_x<\/strong> \u2014 zbi\u00f3r danych znanych warto\u015bci x, kt\u00f3re s\u0105 skorelowane z znane_y<\/em>.<\/li>\n
  • [const]<\/strong> \u2014 argument opcjonalny; ustawienie go na FA\u0141SZ<\/em> powoduje, \u017ce funkcja przeprowadza regresj\u0119 przez punkt (0,0). Domy\u015blna warto\u015b\u0107 (PRAWDA) uwzgl\u0119dnia wyraz wolny w regresji.<\/li>\n<\/ul>\n
    Przyk\u0142ad u\u017cycia:<\/p>\n
    =REGLINX.LINIOWA(10, {2,4,6,8}, {1,2,3,4})<\/code><\/pre>\n
    W tym przyk\u0142adzie prognozujemy warto\u015b\u0107 y dla x r\u00f3wne 10, opieraj\u0105c si\u0119 na znanych zale\u017cno\u015bciach liniowych mi\u0119dzy y a x.<\/p>\n
    Zastosowania praktyczne<\/h2>\n
    Oto kilka praktycznych zastosowa\u0144 funkcji REGLINX.LINIOWA:<\/p>\n
    Analiza trend\u00f3w sprzeda\u017cy<\/h2>\n
    Za\u0142\u00f3\u017cmy, \u017ce dysponujesz danymi dotycz\u0105cymi miesi\u0119cznej sprzeda\u017cy i chcesz prognozowa\u0107 wyniki na kolejny miesi\u0105c, aby zoptymalizowa\u0107 strategie marketingowe. Dane przyk\u0142adowe mog\u0105 wygl\u0105da\u0107 tak:<\/p>\n\n\n\n\n\n\n\n
