Which dimension has the conventional variance estimate that proves to be inadequate with only a 47% probability of correctly estimating the true model and  21% probability of estimating in large samples?

Which dimension has the conventional variance estimate selecting the model with 16% probability which is considerably worse compared to the 4% selection probabilities achieved by the t>2 rule?

In the using of the probability of accurately estimating p for the small sample size of 30, which criterion is favourable?

In which selection dimension, the probabilities of selection a model using PRESS criterion consistently remained significantly lower than those of the t-statistics?

1. The best model is the one with the smallest residual variance.
2. The lowest order lag that lacks significance is dropped from the model.
3. III. The standard error of the regression is frequently utilized as an indicator to assess the model’s performance.

Which section(s) is correct about the AR model?

Which section of 3V for big data are text, photos and videos stated in?

1. Econometrics focuses more on the hypothesis testing, while machine learning is more concerned with formulating the generalization process as an exploration of potential hypotheses.
2. Econometrics gathers the data to assess validity, on the other hand machine learning starts with the data and searches for patterns that fit the data.
3. III. Econometrics gather the data and checks validity of the theory, on the other hand machine learning searches for the theory after gathering the data.
