What should the Mean Squared Error be?

[MSE] Mean Squared Error: MSE measures the performance of the estimator of a machine learning model, it is always positive, and it can be said that estimators with an MSE value close to zero perform better.

MAPE value. how many should it be? Prediction models below

MAPE<10% were classified as having a "high accuracy" degree, and models between < MAPE < were classified as accurate prediction models. and models above P< MAPE are classified as “false and incorrect”.

What does Rmse mean?

root of mean error squares, root mean error squares, mean error squares square root etc. Statistical term translated by definitions and originally abbreviated root mean squared error.

What is MSE Mae?

Mean Squared Error (MSE) / Root Mean Squared Error (RMSE)) Mean Absolute Error (MAE)

How is the mean absolute error calculated?

At actual value and Ft estimated value. The difference between At and Ft is again divided by the actual value At. The absolute value in this calculation is summed for all predicted points in time and divided by the number of matching p points. Multiplying by 100 makes this a percentage of error.

How is the average absolute percent error calculated?

What is a tracking signal?

Monitoring Signal: A measure of whether the forecasting method accurately predicts changes in demand.

What is the R square score?

R² is a statistical measure of how close the data are to the fitted regression line. Also known as coefficient of determination or multiple coefficient of determination for multiple regression. To put it in simpler language, R-square is a measure of fitness for linear regression models.

How to calculate mad?

example:

Step 1: Find the mean of the data: (2 +4+6+8) / 4 = 20/4 = 5. Step 2 : Find the distance between each data and the mean. The distance between 2 and 5 is 3. The distance between 4 and 5 is 1. Step 3 : Add all distances: 3+1+1+3 = 8. Step 4 : Divide this by the number of data: 8 / 4 = 2. The mean absolute deviation is 2.
