The point of the proof is to show that the MSE is minimized by the conditional mean. This is to set the stage for relating the conditional mean to regression (see URL 1 in Andrej's post). clearwater financial services

WebCEF. 3 So, even if the true CEF m (x ) is not linear, linear regression still tells us a certain summary of how the CEF depends on x . This all gets a bit more complicated when there are multiple variables, and more care is needed to relate the regression coe cient for one variable to the CEF when the CEF is nonlinear.

WebIn probability theory, the conditional expectation, conditional expected value, or conditional mean of a random variable is its expected value – the value it would take “on average” over an arbitrarily large number of occurrences – given that a certain set of "conditions" is known to occur.
