Population criterion function
Webminimize a population objective or criterion function. If this criterion function is minimized uniquely at a particular parameter vector, then one can obtain valid confldence regions … WebDec 5, 2024 · Remember, a criterion is case insensitive. Even if we type “william mathew” as the criterion in the above formula, it will produce the same result. Example 2. Let’s see how this function behaves when we deal with numbers. The function works for numbers as efficiently as it does for text values. Suppose we are given the following data:

Webwhich minimizes the population version of the sample criterion. This follows a long tra-dition in econometrics. Goldberger (1991) proposed interpreting the least squares re-gression coefficient vector as the best linear predictor. White (1980a, 1982, 1984, 1994) recommended interpreting parameter values as minimizers of population criterion.
