ISO 5725 uses two terms "trueness" and "precision" to describe the accuracy of a measurement method.
"Trueness" refers to the closeness of agreement between the arithmetic mean of a large number of test results and the true or accepted reference value.
"Precision" refers to the closeness of agreement between test results.
Great Video. Thank you.
thank you so much sir
How can we compare MAPE values of multiple algorithms?
Thank u sir ,how can you connect this to the human capacity of working?
How to measure accuracy in an online method where we can have forecast but dont have real values
if you do not have real values, you cannot calculate errors. that is why we use traning, test samples
@@RESEARCHHUB how can i test accuracy for any online forecasting method ? New data comes in every day. And forecasthorizon is for 30 days and data is in downward trend. The trend change can be non linear.
