Funkce TREND spo\u010d\u00edt\u00e1 hodnoty line\u00e1rn\u00edho trendu.

Syntaxe funkce v Excelu a Google Sheets je definov\u00e1na takto:<\/p>\n

TREND(known_y's, [known_x's], [new_x's], [const])<\/code><\/pre>\n
    \n
  • known_y’s<\/strong> – Toto jsou ji\u017e zn\u00e1m\u00e9 y-hodnoty ve va\u0161\u00ed datov\u00e9 sad\u011b.<\/li>\n

  • [new_x’s]<\/strong> – X-hodnoty, pro kter\u00e9 pot\u0159ebujete vypo\u010d\u00edtat odpov\u00eddaj\u00edc\u00ed y-hodnoty.<\/li>\n
  • [const]<\/strong> – Tento logick\u00fd parametr ur\u010duje, jestli bude ve v\u00fdpo\u010dtu trendov\u00e9 linie zahrnuta konstanta b. Pokud je TRUE nebo je parametr vynech\u00e1n, bude b vypo\u010d\u00edt\u00e1no. Je-li FALSE, konstanta b bude rovna nule a funkce se zam\u011b\u0159\u00ed pouze na v\u00fdpo\u010det sklonu linie.<\/li>\n<\/ul>\n
