Ib txwm faib yog symmetric, unimodal, thiab asymptotic, thiab qhov nruab nrab, nruab nrab, thiab hom yog sib npaug. A ib txwm faib yog zoo kawg nkaus symmetrical nyob ib ncig ntawm nws qhov chaw. Ntawd yog, sab xis ntawm qhov chaw nruab nrab yog daim iav duab ntawm sab laug. Tsuas muaj ib hom, lossis ncov, hauv ib ib txwm faib.
Hais txog qhov no, dab tsi yog ib qho kev faib tawm hauv kev txheeb cais?
Cov ib txwm faib yog qhov ua tau zoo uas piav qhia txog qhov muaj txiaj ntsig ntawm qhov sib txawv li cas faib. Nws yog symmetrical kev faib tawm qhov twg feem ntau ntawm cov kev soj ntsuam pawg nyob ib ncig ntawm lub hauv paus ncov thiab qhov tshwm sim rau qhov tseem ceeb ntxiv deb ntawm qhov txhais tau tias taper tawm sib npaug ntawm ob qho kev qhia.
Ib yam li ntawd, koj txiav txim siab li cas rau kev faib tawm? Qhov nruab nrab, nruab nrab, thiab hom ntawm a ib txwm faib sib npaug. Thaj chaw hauv qab ib txwm nkhaus yog sib npaug rau 1.0. Ib txwm faib yog denser nyob rau hauv nruab nrab thiab tsawg ntom nyob rau hauv cov tails. Ib txwm faib yog txhais los ntawm ob qhov tsis, qhov nruab nrab (Μ) thiab tus qauv sib txawv (σ).
Tom qab ntawd, hom kev faib khoom yog dab tsi?
Muaj ntau ntau qhov sib txawv ntawm qhov yuav tshwm sim kev faib tawm . Qee tus ntawm lawv suav nrog qhov qub kev faib tawm ,,qib kev faib tawm , binomial kev faib tawm , thiab Poisson kev faib tawm . Qhov txawv qhov tshwm sim kev faib tawm ua haujlwm sib txawv thiab sawv cev rau cov txheej txheem tsim cov ntaub ntawv sib txawv.
Dab tsi yog cov khoom ntawm ib txwm faib?
Cov khoom ntawm a ib txwm faib Qhov nruab nrab, hom thiab nruab nrab yog txhua yam sib npaug. Cov nkhaus yog symmetrical ntawm qhov chaw (piv txwv li nyob ib ncig ntawm lub ntsiab lus, Μ). Raws nraim ib nrab ntawm qhov tseem ceeb yog rau sab laug ntawm qhov chaw thiab ib nrab ntawm qhov tseem ceeb yog rau sab xis. Tag nrho cheeb tsam nyob rau hauv lub nkhaus yog 1.

Cov zis yog hais txog cov lus hais lossis sau cov ntaub ntawv uas koj tsim siv hom lus thib ob. Yam koj tsim yog qhov tshwm sim ntawm qhov koj tau txais lossis kawm
