The program is based on the powerful model-free method of time series analysis Caterpillar-SSA (Singular Spectrum Analysis). The result of the Caterpillar-SSA processing is identification, analysis and forecast of additive components of time series (trends, periodicities, noise). The program can be applied to multivariate analysis/forecasting and change-point detection. Keywords: time series forecast analysis trend periodicities seasonalities statistics ssa software principal component decomposition singular value svd reconstruction approximation spectrum |

Freeware for fast development and application of regression/approximation type networks including the multilayer perceptron, functional link network, piecewise linear network, self organizing map and K-Means. C source code for applying trained networks. Extensive help, utilities for pre-processing and file handling, and training data are also provided. User-supplied txt-format training data files, containing rows of numbers, can be of any size.

SurGe is a computer program which enables to generate a surface as an interpolation (approximation) function of two independent variables; implements an interpolation / approximation method called ABOS which produces a surface comparable to a surface created by Kriging or Minimum curvature method. Keywords: mapping software surface interpolation approximation kriging minimum curvature mapping package surface interpolation approximation |
