c) Relative error and (d) percentage error
Answers
Answer:
a. In statistics, mean absolute error (MAE) is a measure of errors between paired observations expressing the same phenomenon. MAE is calculated as: It is thus an arithmetic average of the absolute errors , where is the prediction and. the true value.
b. The approximation error in some data is the discrepancy between an exact value and some approximation to it. An approximation error can occur because: the measurement of the data is not precise due to the instruments.
relative error is also known as approximation error .
c. Percent error is the difference between estimated value and the actual value in comparison to the actual value and is expressed as a percentage. In other words, thepercent error is the relative error multiplied by 100.
