Ib qho ntawm lub npe nrov tshaj plaws uas tsis yog lub tsev kawm theem pib ua haujlwm uas tau siv hauv kev ua lej, hauv txoj kev xav ntawm qhov sib txawv ntawm qhov sib luag, hauv kev txheeb cais thiab hauv qhov kev kwv yees qhov kwv yees yog Laplace muaj nuj nqi. Kev daws teeb meem nrog nws yuav tsum muaj kev npaj ntau. Cia peb kawm saib koj yuav siv li cas Excel cov cuab yeej los laij ntsuas qhov ntsuas no.

Laplace muaj nuj nqi

Laplace muaj nuj nqi tau siv ntau thiab kev siv theoretical. Piv txwv, feem ntau nws siv los daws cov kab zauv sib txawv. Lo lus no muaj lwm lub npe sib npaug - qhov yuav tshwm sim muaj. Hauv qee kis, lub hauv paus ntawm kev daws yog qhov tsim ntawm lub rooj ntawm qhov tseem ceeb.

Tus neeg teb xov tooj NORM.ST.RASP

Hauv Excel, qhov teeb meem no tau daws tau siv tus neeg teb xov tooj NORM.ST.RASPCov. Nws lub npe yog luv ntawm lo lus "tus qauv kev faib tawm". Txij li nws txoj haujlwm tseem ceeb yog rov qab mus rau xaiv kab ntawm cov xov tooj hluav taws xob ib txwm txheem kev faib khoom. Tus neeg teb xov tooj no zwm rau hom kev ua ntawm cov qauv Excel ua haujlwm.

Hauv Excel 2007 thiab hauv cov txheej txheem ua ntej, cov lus no tau hu NORMSTRASPCov. Tshuav rau kev siv tau yooj yim hauv cov khoos phis tawm tshiab tam sim no. Tab sis tseem, lawv pom zoo kom siv cov analogue siab dua - NORM.ST.RASP.

Tus Neeg Teb Xov Tooj Syntax NORM.ST.RASP zoo li no:

= NORM.ST. RASP (z; kev ntxiv)

Tus Neeg Teb Xov Tooj Tsis Zoo NORMSTRASP yog sau zoo li no:

= NORMSTRASP (z)

Raws li koj tuaj yeem pom, hauv cov tshiab tshiab rau qhov kev sib cav uas twb muaj lawm "Z" kev sib cav ntxiv "Kev"Cov. Nws yuav tsum raug sau tseg tias txhua qhov kev sib cav yuav tsum muaj.

Sib cav "Z" qhia txog cov nuj nqis hais txog yam uas txoj kev faib tawm raug tsim ua.

Sib cav "Kev" sawv cev lub laj thawj muaj nuj nqis uas yuav muaj lub tswv yim "TSEEM" ("1") lossis TSIS THAM ("0")Cov. Hauv thawj kis, txoj haujlwm xa mus rau qhov tseem ceeb rov qab rau hauv lub xovtooj qhia, thiab hauv ob, qhov hnyav faib tawm txoj haujlwm.

Teeb meem daws teeb meem

Txhawm rau kom ua qhov xav tau qhov kev suav rau ib qho sib txawv, cov qauv hauv qab no tau thov:

= NORM.ST. RASP (z; qhov tseem ceeb (1)) - 0.5

Tam sim no cia peb saib ib qho piv txwv tshwj xeeb siv tus neeg teb xov tooj NORM.ST.RASP kom daws tau qhov teeb meem tshwj xeeb.

  1. Xaiv lub xov tooj ntawm qhov ua tiav tiav yuav tshwm thiab nyem rau ntawm lub cim "Ntxig ua haujlwm"nyob ze ntawm kab ntawm cov qauv.
  2. Tom qab qhib Muaj nuj nqi Wizards mus rau qeb "Xov Xwm" lossis "Ua tiav cov npe niam ntawv"Cov. Xaiv lub npe NORM.ST.RASP thiab nias rau pob "OK".
  3. Tus neeg teb xov tooj cav sib cav tau qhib NORM.ST.RASPCov. Hauv dab teb "Z" peb qhia qhov sib txawv rau qhov uas koj xav suav. Tsis tas li, qhov kev sib cav no tuaj yeem sawv cev tau raws li siv rau hauv lub cell uas muaj qhov hloov no. Hauv dab teb "Kev tseem ceeb"nkag mus rau tus nqi "1"Cov. Qhov no txhais tau hais tias tus neeg teb xov tooj tom qab kev suav yuav rov qab xa mus rau qhov kev faib tawm yam muaj nuj nqi raws li kev hais daws. Tom qab cov haujlwm saum toj no ua tiav, nyem rau ntawm lub pob "OK".
  4. Tom qab ntawd, qhov tshwm sim ntawm cov ntaub ntawv ua los ntawm tus neeg teb xov tooj NORM.ST.RASP yuav muab sau rau lub thawv qhia hauv thawj kab lus ntawm phau ntawv no.
  5. Tab sis hais tias tsis yog txhua txhua. Peb suav tsuas yog qhov standard normal integral distribution. Txhawm rau xam tus nqi ntawm Laplace muaj nuj nqi, koj yuav tsum rho tus lej los ntawm nws 0,5Cov. Xaiv lub xov tooj ntawm lub ntsej muag. Hauv tus qauv bar tom qab qhia nqe lus NORM.ST.RASP ntxiv tus nqi: -0,5.
  6. Txhawm rau ua qhov kev xam, nyem rau ntawm lub pob SauCov. Qhov tshwm sim tau yuav yog qhov xav tau tus nqi.

Raws li koj tuaj yeem pom, nws tsis yog qhov nyuaj los xam Laplace kev ua haujlwm rau ib qho tshwj xeeb muab cov nqi hauv Excel. Rau cov laj thawj no, cov neeg siv lag luam tus qauv siv. NORM.ST.RASP.
