since the promenades allocate the part of the country's revenues, therefore, attention to its valuation is very important. springs in desert area are the most prominent of natural landscapes. more study in country investigates recreational value using double– bounded dichotomous choice. but in this study, single-bounded dichotomous choice has been used because of this approach is more like...

In many different contexts, decision-making is improved by the availability of probabilistic predictions. The accuracy forecasting methods can be compared using scoring functions and insight provided calibration tests. These tests evaluate consistency predictions with observations. Our main agenda in this paper interval forecasts their evaluation. Such are usually bounded two quantile forecasts...
