The traditional combination forecasting model has good effect, but it needs precise historical data. In fact, many random events are uncertain, and much of the data imprecise; sometimes, lacking. We need to study problems by means uncertainty theory. Uncertain least squares estimation is an important technique uncertain statistics, way deal with imprecise data, one best methods solve unknown pa...

The objective of this research was to develop a mathematical and statistical model for long-term prediction. Extreme Value Theory (EVT) applied analyze the appropriate distribution by using peak-over-threshold approach with Generalized Pareto Distribution (GPD) predict daily extreme precipitation temperatures in eight provinces located upper northeastern region Thailand. Generally, each provinc...

It is shown that, by applying a principle of information theory, one obtains Berry's conjecture regarding the high-lying quantal energy eigenstates of classically chaotic systems. 1 In many problems of physical interest, it is necessary to abandon a search for the exact solution, and to turn instead to a statistical approach. This involves mentally replacing the answer which we seek, with an en...
