In contrast to the mean absolute percentage error, SMAPE has both a lower bound and an upper bound. Indeed, the formula above provides a result between 0% and 200%. Indeed, the formula above provides a result between 0% and 200%.

Confusingly, sometimes when people refer to wMAPE they are talking about a different model in which the numerator and denominator of the wMAPE formula above are weighted again by another set of custom weights .
Forecast errors can be evaluated using a variety of methods namely mean percentage error, root mean squared error, ... but it can’t move up 20-30%”; ...
As a percentage of the total expenditure; As a total percentage including and above the original budget; As a percentage of the cost overruns to original budget; For example, consider a bridge with a construction budget of $100 million where the actual cost was $150 million. This scenario could be truthfully represented by the following statement
A sieve analysis (or gradation test) is a practice or procedure used in geology, civil engineering, and chemical engineering to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the ...
Say you earn an income of $2,000 a month. Following the 50/30/20 rule would mean allocating $1,000 to needs, $600 to wants and $400 to savings or high-interest debt. But if your monthly rent and ...
A cost estimate is the approximation of the cost of a program, project, or operation. The cost estimate is the product of the cost estimating process. The cost estimate has a single total value and may have identifiable component values. A problem with a cost overrun can be avoided with a credible, reliable, and accurate cost estimate.
