This paper investigates the forecasting performance of different time-varying BVAR models for Iranian inflation. Forecast accuracy of a BVAR model with Litterman’s prior compared with a time-varying BVAR model (a version introduced by Doan et al., 1984); and a modified time-varying BVAR model, where the autoregressive coefficients are held constant and only the deterministic components are allo...
The paper analyzes the melting pace of ice cap in the North Pole and its influence on the rising sea level. The paper constructs the linear and non-linear models between rising sea level and the year by quoting data from Florida Tide Gage Station. The paper also contrasts the two models and selects the non-linear model. By adopting the model, the paper predicts the height of rising sea level ev...
Background and aims: Since accurate forecasts help inform decisions for preventive health-careintervention and epidemic control, this goal can only be achieved by making use of appropriatetechniques and methodologies. As much as forecast precision is important, methods and modelselection procedures are critical to forecast precision. This study aimed at providing an overview o...
in this paper semi-markov models are used to forecast the triple dimensions of next earthquake occurrences. each earthquake can be investigated in three dimensions including temporal, spatial and magnitude. semi-markov models can be used for earthquake forecasting in each arbitrary area and each area can be divided into several zones. in semi-markov models each zone can be considered as a state...

Purpose: The purpose of this paper is to develop a combined model composed of greyforecast model and Logistic-growth-curve model to improve the accuracy of forecast model of cargo throughput for the port. The authors also use the existing data of a current port to verify the validity of the combined model. Design/methodology/approach: A literature review is undertaken to find the appropriate fo...
Determination and the estimation of the house price in urban areas has a great importance for governments, individual and state investors and common people. The mentioned estimation can be used in future planning and decision making of many urban and regional policies. In this regard, due to the vital importance of the house price in recent decades powerful and effective functions have been use...
Executive Summary 5 A method for solar forecasting using cloud motion vectors (CMV) from satellite imagery with the 6 ability to characterize forecast uncertainty has been developed. On average, the root mean square error 7 (RMSE) for CMV forecast increases with increasing forecast horizon and becomes larger than the North 8 American Model (NAM, a numerical weather prediction model) forecast er...
