  • SMT : a spatial mapping tool for statistical data set
  • Using the GIS techniques, and supported by Auto CAD software, the A. develops a practical method to make statistical maps and a software (SMT) to make small-scale statistical maps using C language.

  • . Rock-cored drumlins are more morphologically diverse and occur on high-level plateaus and upland flanks. Morphometric analysis reveals both spatial and statistically significant absolute differences between the elongation ratios and orientations

  • Consumer behaviour ; Distance ; Error ; Model ; Simulation ; Spatial choice ; Statistics ; Trip ; Utility fonction
  • In the presence of correlation between error terms in set delineation and choice selection, statistical estimators are biased (selection bias). An alternative two-stage method is proposed to estimate parameters of set delineation and choice

  • Statistical modelling and prediction of pollutants in the urban atmosphere of Salamanca, Spain
  • 1997
  • Two modifications of this model, accounting for the long lines effect are proposed. The first modification deals with the instant reaction of customers at long queues and incorporates the statistical dependence of their behaviour. In the second
  • model customer behaviour is determined by past data, which make their behaviour statistically independent. The concept of self-consistent distribution is introduced, its existence is investigated, and properties of self-consistent distributions
