One supposed problem with SMAPE is that it is not symmetric since over- and under-forecasts are not treated equally. The following example illustrates this by applying the second SMAPE formula: Over-forecasting: A t = 100 and F t = 110 give SMAPE = 4.76%; Under-forecasting: A t = 100 and F t = 90 give SMAPE = 5.26%.
Forecasting is the process of making predictions based on past and present data. Later these can be compared with what actually happens. For example, a company might estimate their revenue in the next year, then compare it against the actual results creating a variance actual analysis.
Climate Prediction Center monitors and forecasts short-term climate fluctuations and provides information on the effects climate patterns can have on the nation. Environmental Modeling Center develops and improves numerical weather, climate, hydrological and ocean prediction through a broad program in partnership with the research community.

We simulated a Nov. 8 election 10 million times using our state-by-state averages. In 9.8 million simulations, Hillary Clinton ended up with at least 270 electoral votes. Therefore, we say Clinton has a 98.0 percent chance of becoming president.
In educational assessment, T-score is a standard score Z shifted and scaled to have a mean of 50 and a standard deviation of 10. [ 14 ] [ 15 ] [ 16 ] In bone density measurements, the T-score is the standard score of the measurement compared to the population of healthy 30-year-old adults, and has the usual mean of 0 and standard deviation of 1.
Propensity scores are used to reduce confounding by equating groups based on these covariates. Suppose that we have a binary treatment indicator Z, a response variable r, and background observed covariates X. The propensity score is defined as the conditional probability of treatment given background variables:
USD/MXN exchange rate. Mexican peso crisis in 1994 was an unpegging and devaluation of the peso and happened the same year NAFTA was ratified. [2]The Mexican peso (symbol: $; currency code: MXN; also abbreviated Mex$ to distinguish it from other peso-denominated currencies; referred to as the peso, Mexican peso, or colloquially varo) is the official currency of Mexico.
