For what type of data is a histogram appropriate?

Question 2

How do the MAD and MSE criteria differ in their approach to evaluating the fit of an estimation equation to a time series?

Answer to Question 1

Interval data.

Answer to Question 2

MAD considers the mean absolute error from the actual data; the direction of the error is not considered. In calculating MAD, the absolute values of the deviations are used. MSE considers the mean squared error from the actual data. In calculating MSE, the squared deviations from the actual data are used. The MSE approach penalizes large errors more since the errors are squared.

Both answers were spot on, thank you once again
