- The mean absolute error, mean squared error, and mean absolute percentage error are all methods to measure the accuracy of a forecast. These methods measure forecast accuracy by a. determining how well a particular forecasting method is able to reproduce the time series data that are already available. b. using the current value to estimate how well the model generates previous values correctly. c. predicting the future values and wait for a pre-defined time period to examine how accurate the predictions were. d. adjusting the scale of the data.
- In the presence of correlated observations, the OLS estimators are unbiased, but their estimated standard errors are inappropriate. Which of the following could happen as a result?-The model looks better than it really is with a spuriously high R2-The F test may suggest that the predictor variables are individually and jointly significant when this is not true-All of the answers are correct-The t test may suggest that the predictor variables are individually and jointly significant when this is not true
- Place the steps of the holdout method in the proper order:We partition the sample data into two parts, labeled training set and validation set correct toggle button unavailableWe use the training set to estimate competing models. correct toggle button unavailableWe use the estimates from the training set to predict the response variable in the validation set correct toggle button unavailableWe calculate the accuracy rate for each competing model. The preferred model will have the smallest RMSE (or the largest accuracy rate).
