Cov lus teb raug yog b) Seb cov qhab nia ib txwm raug faib. Qhov no yog vim qhov kev xeem Kolmogorov–Smirnov piv cov qhab nia hauv cov qauv mus rau ib txwm faib cov qhab nia zoo ib yam thiab tus qauv sib txawv.

Puas Kolmogorov Smirnov kuaj rau qhov qub?

Kev xeem Kolmogorov-Smirnov yog siv los ntsuas qhov kev xav tsis zootias cov ntaub ntawv los ntawm kev faib tawm ib txwm. Qhov kev xeem Kolmogorov Smirnov tsim cov ntawv txheeb cais uas tau siv (nrog rau qib kev ywj pheej) los ntsuas qhov qub.

Kolmogorov Smirnov yog hom kev xeem twg?

Hauv kev txheeb cais, qhov kev xeem Kolmogorov–Smirnov (K-S xeem lossis KS xeem) yog ib qho kev ntsuas tsis sib luag ntawm kev sib npaug ntawm kev sib npaug (lossis tsis tu ncua, saib Tshooj 2.2), Ib-dimensional probability distributions uas yuav siv tau los sib piv ib tug piv txwv nrog ib tug reference probability distributions (ib-sample K–S test), los yog muab piv ob …

Dab tsi yog qhov kev xav ntawm Kolmogorov Smirnov xeem?

Kev xav. Qhov kev xav tsis tseeb yog ob qho qauv yog randomly kos los ntawm tib yam (pooled) cov nqi. Ob qho piv txwv yog kev ywj pheej. Qhov ntsuas qhov ntsuas yog qhov tsawg kawg nkaus.

Kuv yuav kuaj kuv qhov kev xeem Kolmogorov Smirnov li cas?

Txoj kauj ruam dav dav

  1. Tsim ib qho EDF rau koj cov ntaub ntawv qauv (saib Empirical Distribution Function rau cov kauj ruam),
  2. Qhia tus niam txiv faib (piv txwv li ib qho uas koj xav muab piv rau koj EDF rau),
  3. Kaw ob qhov kev faib ua ke.
  4. ntsuas qhov ntsug qhov deb tshaj plaws ntawm ob daim duab.
  5. Xaiv qhov ntsuas ntsuas.
