Spearman's Rho yog ib qho kev ntsuas tsis yog parametric siv los ntsuas lub zog ntawm kev sib koom ua ke ntawm ob qhov sib txawv, qhov twg tus nqi r = 1 txhais tau tias ib tug zoo meej correlation thiab tus nqi r = -1 txhais tau tias kev sib raug zoo tsis zoo.
Ua li no, vim li cas koj thiaj siv Spearman's rho?
Spearman's rho yog ib qho kev ntsuas tsis yog parametric ntawm kev sib raug zoo uas tso cai rau tus kws tshawb fawb rau txiav txim siab qhov tseem ceeb ntawm lawv qhov kev tshawb nrhiav. Nws yog siv hauv kev tshawb fawb ntawd yog nrhiav kev sib raug zoo, qhov twg cov ntaub ntawv yog yam tsawg kawg nkaus.
Qhov txawv ntawm Spearman thiab Pearson yog dab tsi? Cov qhov sib txawv ntawm tus Pearson correlation thiab Spearman correlation yog qhov Pearson yog qhov tsim nyog tshaj plaws rau kev ntsuas los ntawm qhov ntsuas lub sijhawm, thaum lub Spearman Nws yog qhov tsim nyog rau kev ntsuas ntsuas los ntawm cov ntsuas ntsuas.
Kuj Paub, koj txhais li cas Spearman tus rho?
Cov Spearman kev sib raug zoo coefficient, rs, tuaj yeem coj qhov tseem ceeb ntawm +1 txog -1. Ib rs ntawm +1 qhia txog kev sib koom ua ke zoo tshaj plaws ntawm qib, a rs ntawm xoom qhia tias tsis muaj kev sib raug zoo ntawm qib thiab rs ntawm -1 qhia txog kev sib koom ua ke tsis zoo ntawm qib. Qhov ze rs yog mus rau xoom, lub weaker lub koom haum ntawm cov qeb.
Thaum twg kuv yuav tsum siv Spearman correlation?
Spearman kev sib raug zoo feem ntau yog siv los soj ntsuam kev sib raug zoo nrog cov kev hloov pauv. Piv txwv li, koj yuav siv a Spearman kev sib raug zoo los soj ntsuam seb qhov kev txiav txim uas cov neeg ua haujlwm ua tiav ib qho kev sim ua rau muaj feem cuam tshuam nrog rau lub hlis uas lawv tau ua haujlwm.

Koj txhais qhov hnyav txhais li cas?
Cov ntsiab lus. Weighted Mean: Ib qho txhais tau tias qee qhov txiaj ntsig pab ntau dua li lwm tus. Thaum qhov hnyav ntxiv rau 1: tsuas yog muab txhua qhov hnyav los ntawm tus nqi sib xws thiab suav tag nrho. Txwv tsis pub, muab txhua qhov hnyav w los ntawm nws qhov sib piv tus nqi x, suav tias tag nrho, thiab faib los ntawm qhov sib npaug ntawm qhov hnyav: Qhov Ntsuas Ntsuas = ΣwxΣw
Cov ntsiab lus hydrophilic thiab hydrophobic txhais li cas thiab lawv cuam tshuam li cas?
Hydrophobic txhais tau hais tias cov molecule yog "ntshai" dej. Cov tails ntawm phospholipid yog hydrophobic, txhais tau tias lawv nyob hauv daim nyias nyias. Hydrophilic txhais tau hais tias cov molecule muaj affinity rau dej
Koj txhais li cas los ntawm lo lus txhais?
Lub ntsiab lus txhais yog ib nqe lus ntawm lub ntsiab lus ntawm ib lo lus (ib lo lus, kab lus, lossis lwm yam cim). Cov lus txhais tau muab faib ua ob pawg loj, cov ntsiab lus tsis txaus ntseeg (uas sim muab lub ntsiab lus ntawm lub ntsiab lus) thiab cov ntsiab lus txuas ntxiv (uas sim sau cov khoom uas ib lo lus piav qhia)
Txhais tau li cas los txhais ib daim duab peb sab?
Kev txhais lus. Kev txhais lus yog ib qho kev hloov pauv uas tshwm sim thaum ib daim duab tau txav los ntawm ib qho chaw mus rau lwm qhov chaw yam tsis tau hloov nws qhov loj, duab lossis kev taw qhia. Txhawm rau txhais cov ntsiab lus P (x, y), ib chav nyob sab xis thiab b units, siv P'(x + a, y + b)
Yuav ua li cas rho tawm rho tawm haujlwm?
Rho dependent termination yog ib qho ntawm ob hom kev txiav tawm hauv prokaryotic transcription, lwm qhov yog intrinsic (los yog Rho-independent). Tom qab khi rau cov saw tshiab RNA, ρ qhov tseem ceeb txav mus raws cov molecule hauv 5'-3' kev taw qhia thiab txhawb kev sib cais los ntawm DNA qauv thiab RNA polymerase
