Jeffrey Marc Wooldridge (born 1960) is an American econometrician. He is a University Distinguished Professor in the Department of Economics at Michigan State University . Wooldridge is known for his theoretical contributions to the analysis of cross-sectional and panel data .
Suppose that we model our data as = + + +. If we split our data into two groups, then we have = + + + and = + + +. The null hypothesis of the Chow test asserts that =, =, and =, and there is the assumption that the model errors are independent and identically distributed from a normal distribution with unknown variance.

In the following exposition, we follow the treatment in Wooldridge. [1] Particularly, the asymptotic derivation is done under fixed-T, growing-N setting. Writing the conditional density of y it given x it as f t (y it | x it;θ), the partial maximum likelihood estimator solves:
Econometrics is an application of statistical methods to economic data in order to give empirical content to economic relationships. [1] More precisely, it is "the quantitative analysis of actual economic phenomena based on the concurrent development of theory and observation, related by appropriate methods of inference."
The theorem, later associated with Frisch, Waugh, and Lovell, and Yule's partial regression notation, were included in chapter 10 of Yule's successful statistics textbook, first published in 1911. The book reached its tenth edition by 1932. [9] In a 1931 paper co-authored with Mudgett, Frisch explicitly quoted Yule's results. [10]

The function h(V) is effectively the control function that models the endogeneity and where this econometric approach lends its name from. [4]In a Rubin causal model potential outcomes framework, where Y 1 is the outcome variable of people for who the participation indicator D equals 1, the control function approach leads to the following model
