Kev soj ntsuam ntawm qhov muaj zog ntawm qhov ntsuas pib pib nrog qhov lawv hloov pauv (nce ntxiv, txo qis lossis tsis hloov pauv) qhov tshwj xeeb thiab cov lus sib piv. Txhawm rau taug qab qhov kev hloov pauv hauv cov xwm txheej ntawm lub sijhawm dhau los, cov ntsuas raug suav: qhov hloov pauv kiag li, kev hloov pauv ntawm tus kheej, tus nqi pauv hloov.
Cov Lus Qhia

Thov nco ntsoov tias tag nrho cov ntsuas no tuaj yeem yog qhov pib, thaum theem ntawm ib lub sijhawm piv nrog theem ntawm lub sij hawm pib, thiab cov saw hlau, thaum theem ntawm ob lub caij nyoog nyob ib sab piv.

Koj tuaj yeem suav qhov pib hloov pauv (tsis paub meej) raws li qhov sib txawv ntawm qhov tshwj xeeb thiab qib theem ntawm koob: Y (b) = Y (i) - Y (1). Nws qhia tau ntau npaum li cas theem ntawm lub sijhawm tshwj xeeb yog siab dua lossis qis dua qib pib. Kev hloov pauv uas tsis txawv txav yog qhov sib txawv ntawm qhov tshwj xeeb thiab qib qib dhau los ntawm cov koob: Y (q) = Y (i) - Y (i-1). Nws qhia tau hais tias muaj pes tsawg qhov kev ua nyob rau theem ntawm qee lub caij nyoog siab dua lossis qis dua yav dhau los ib. Nco ntsoov tias muaj kev sib ze ntawm lub hauv paus thiab cov saw hloov pauv: qhov sib xyaw ntawm cov saw qhov hloov mus rau qhov kawg yog sib luag ntawm qhov hloov pauv kawg.

Thaum txheeb xyuas qhov ua tau zoo ntawm qhov ua kom zoo, koj tuaj yeem suav lub hauv paus kev hloov pauv (hauv paus ntawm kev loj hlob ntawm lub hauv paus). Nws sawv cev qhov sib piv ntawm qhov taw qhia tshwj xeeb rau thawj ntawm tus lej ntawm lub zog: Kuv (b) = Y (i) / Y (1). Kev hloov pauv ntawm cov txheeb ze yog qhov sib piv ntawm qhov tshwj xeeb thiab qib dhau los ntawm koob: I (c) = Y (i) / Y (i-1). Qhov hloov ntawm tus txheeb ze tau qhia tias muaj pes tsawg zaus ntawm qib ntawm ib kab muab yog qhov ntau dua li qib ntawm cov kab yav dhau los, lossis feem dab tsi ntawm nws yog. Qhov kev hloov pauv ntawm tus txheeb ze tuaj yeem tshaj tawm raws li feem pua los ntawm cov khoo khoo sib piv nrog 100%. Muaj kev sib raug zoo ntawm cov saw thiab cov hloov pauv txheeb ze: cov khoom ntawm cov saw kev hloov pauv yog sib npaug ntawm qhov kawg ntawm ib qho.

Ntxiv mus, thaum txheeb xyuas qhov kev ua haujlwm ntawm qhov ntsuas, koj tuaj yeem laij seb qhov hloov pauv (kev loj hlob) ntawm ntau npaum li cas. Nov yog qhov ntsuas kwv yees qhia tau pom tias pes tsawg feem pua ntawm qhov ntsuas tau muab ntau dua lossis tsawg dua lwm tus, coj los ua qhov sib piv. Nws yog txiav txim los ntawm kev rho tawm 100% los ntawm kev sib txheeb ntawm cov txheeb ze lossis cov saw hloov: T (i) = Kuv (i) - 100%.
