Ib qho kev sib txawv endogenous yog qhov sib txawv hauv cov qauv kev txheeb cais uas tau hloov lossis txiav txim siab los ntawm nws txoj kev sib raug zoo nrog lwm qhov sib txawv hauv tus qauv… Yog li ntawd, nws qhov tseem ceeb yuav raug txiav txim los ntawm lwm qhov sib txawv. Endogenous variables yog qhov opposite ntawm exogenous variables, uas yog ywj siab variables los yog sab nraud rog.
Yuav ua li cas piv txwv ntawm endogenous variables?
Examples of Endogenous Variable

- Nyiaj tau los. Hauv cov qauv kev lag luam lossis kev txheeb cais uas suav nrog cov nyiaj tau los, nws raug suav tias yog qhov sib txawv ntawm qhov kawg. …
- Tus nqi paj. …
- Agriculture. …
- Kev Kawm.
Yuav ua li cas yog cov piv txwv ntawm exogenous variable?
Ib qho txawv txav txawv txav yog qhov sib txawv uas tsis cuam tshuam los ntawm lwm qhov sib txawv hauv qhov system. Piv txwv li, coj ib qho yooj yim causal system xws li kev ua liaj ua teb. Kev hloov pauv xws li huab cua, kev txawj ua liaj ua teb, kab tsuag, thiab muaj cov noob yog tag nrho exogenous rau qoob loo.
Nws yog ib qho piv txwv ntawm Endogeneity?
Piv txwv piav txog ntau hom endogeneity. Ib tug neeg muag khoom ice cream muag ice cream cream on a beach. Nws sau cov ntaub ntawv rau tag nrho kev muag khoom (Y) thiab muag tus nqi (X) rau 2 xyoos. Nws muab cov ntaub ntawv rau tus kws tshawb fawb cov ntaub ntawv thov kom nws nrhiav tus nqi muag zoo.
Koj paub li cas yog qhov sib txawv yog endogenous?
Ib variable xj yog hais tias yog endogenous nyob rau hauv lub causal qauv M yog nws tus nqi yog txiav txim los yog cuam tshuam los ntawm ib los yog ntau tshaj ntawm cov kev ywj pheej variables X(tsis suav nws tus kheej). Qhov sib txawv ntawm endogenous purely yog ib qho tseem ceeb uas tau txiav txim siab tag nrho los ntawm cov xeev ntawm lwm qhov sib txawv hauv qhov system.
