问题		答案
Time-varying covariates 开始学习		variables that change for the same entity over time.
Time-invariant characteristics 开始学习		Attributes that do not change over time within entities
Individual Specific Effects 开始学习		unique characteristics associated with each cross-sectional unit in the dataset.
Observable factors 开始学习		measurable variables that influence the dependent variable
Unobservable factors 开始学习		hidden variables that affect the dependent variable
Fixed effects 开始学习		Fixed effects capture unobserved variables that are constant over time but vary between entities.
Random Effects 开始学习		effects that assume random variation between entities in intercepts and slopes.
Between Estimator 开始学习		An estimator that uses the variation between individuals, ignoring the within-individual changes.
Within Estimator 开始学习		Another term for fixed effects estimators; refers to estimating relationships using only within-individual variation.
Instrumental Variables 开始学习		Variables that help control for endogeneity by being correlated with the endogenous explanatory variable but not with the error term.
