Popis a syntaxe funkce NEGBINOMDIST<\/h2>\n

Funkce NEGBINOMDIST, zn\u00e1m\u00e1 v \u010de\u0161tin\u011b jako NEGBINOMDISTRO, je v MS Excel a Google Sheets u\u017e\u00edv\u00e1na pro v\u00fdpo\u010det pravd\u011bpodobnost\u00ed v r\u00e1mci negativn\u00ed binomick\u00e9 distribuce. Jedn\u00e1 se o distribuci, kter\u00e1 se pou\u017e\u00edv\u00e1 v p\u0159\u00edpadech, kdy je experiment opakov\u00e1n do chv\u00edle, ne\u017e dos\u00e1hneme stanoven\u00e9ho po\u010dtu \u00fasp\u011bch\u016f, p\u0159i\u010dem\u017e ka\u017ed\u00fd pokus je nez\u00e1visl\u00fd a m\u00e1 stejnou pravd\u011bpodobnost \u00fasp\u011bchu.<\/p>\n

V Google Sheets je pot\u0159eba pou\u017e\u00edvat hodnoty 1 (pro kumulativn\u00ed) a 0 (pro pravd\u011bpodobnostn\u00ed).<\/li>\n<\/ul>\n

    Zde jsou uvedeny dva praktick\u00e9 p\u0159\u00edklady pou\u017eit\u00ed NEGBINOMDIST:<\/p>\n
    P\u0159\u00edklad 1: Kontrola kvality<\/h2>\n
