WebNov 3, 2024 · 2. Running an OLS estimator: The OLS regression takes the form: Y = μ O L S + τ O L S D + ε. The coefficient ( μ O L S, τ O L S) are constructed to minimize MSE, and will satisfy the exogeneity condition. The OLS coefficient of τ is equal to. τ O L S = E [ D Y] E [ D] − E [ ( 1 − D) Y] E [ 1 − D] 3. WebMay 24, 2011 · Conditional Expectation Function (CEF) or Population Regression Function (PRF) or Population Regression (PR) - It states merely that the expected value of the distribution of Y given Xi is functionally related to Xi. In simple terms, it tells how the mean or average response of Y varies with X.
