Approximation Software

SurGe

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.

Numap7

Freeware for fast training, validation, and application of regression/approximation networks including the multilayer perceptron, functional link network, piecewise linear network, self organizing map and K-Means. C source 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.

CaterpillarSSA

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.

LeoStatistic

Statistical analysis of experimental data. An automatically selection of applicable presentation for given combination of numbers of arguments and values with flexibility in choosing suitable interface to fit data with diverse of formulas. Input of data: copy/paste, database table, text file, image. Statistical schemes include probability distribution, curve and surface fit, near neighbors method. Results can be saved as bitmap and formulas.
