For shorter horizons, there were other forecasts that could be seen as at least as good as the random walk, but with higher MFSE. As for the forecasts from one to three quarters, some models were considered equivalent to the random walk.
Contrary to the previous case, there are other forecasts that can be seen as at least as good as the random walk, but with higher MFSE, up to five quarters.
For all horizons, the random walk is not the best model when the metric is the MFSE. For one, two, and five quarters ahead, the random walk has the lowest mean squared error.
For the horizons one, two, three, and five quarters ahead, the best model using the MFSE criteria is a model that combines the random walk and some structural model.
“We are delighted to announce the successful re-creation of our mFSE Solution for the iPhone and its availability on the SAP Store,” said Prashant Parekh, Founder and CEO of KloudData.
Specifically, the mFSE app provides field service employees with mobile access to job assignments, scheduling, inventory status, priority tasks, pricing, locations, maps, order history, feedbacks and more.
