Comprehensive tool for statistical analysis and modeling of experimental and market data.
Universal input from outside data sources: from text or database files; file type and edit in spreadsheet like control; copy/paste from spreadsheets applications like MS Excel or Access; extract curve in numerical form from image chart; image file.
Data manipulation procedures permit to new create and modify existing variables using simple formulas or schemes. Syntax of formulas incorporates itself ability to use indexing variables that permit to create differential variables.
Statistical schemes of the program incorporate: distribution of one variable with comparison T, Erlang and Poisson probability; conditional distribution depend on values of other parameters; two arguments distribution with 3D presentation or color map presentation; curve fitting with variety schemes to define modeling formula; peaks revealing with base line elimination and special emphasizing on mass chromatogram; 3D presentation of function of two arguments and with plane, parabolic and user formula multivariate approximation; near neighbors method for multivariate estimation; creating score variable that reflect probability for given variable be large then chosen number and algorithm for calculation of the score from other significant parameters.
Found approximated coefficients are accompanied with their calculated standard deviations. The accuracy of presentation of their numerical values can be set by user or automatically defined on the base of stability of their computation. Automatically run a comprehensive statistical analysis by one mouse click.
Convenient user interface permits to design professional looking visualization of the data and modeling formulas. Color, size and shape of point marks and formula lines as well elements of graphic including font of the description could be easy modified. A report of present statistical analysis can be saved in form of MS Word document or HTML page.

Calculation Made Easy Ver 4. 1 is an electronic math flashcards program. It has drills written to teach children (even adults) Tables, Addition, Subtraction, Multiplication, and Division.

The Number Base converter is a tool which converts numbers from one base to another such as binary, decimal, hex, octal. The program is quite simple so even if you are a beginner you can use it without any trouble.

This application is a laboratory for the creation of automata. An automaton is a system of circles moving relative to one another in a hierarchical fashion which create cruves which are a superset of epicycloids and hypocycloids.

This application demonstrates the curious relationships wherein a tetrahedron can be inscribed in a cube in two different ways and a cube can be inscribed in a dodecahedron in 5 different ways.

Visualize a 3-dimensional golden-rectangular-solid that is analagous to the 2-dimensional golden-rectangle, which can be sub-divided recursively so that each left-over rectangular solid has the same proportions as the original rectangle.

Phyllotaxis is the study of the successive arrangement of radial parts of a growing plant, such as the leaves on a stem, or the seeds in the head of a sunflower. This application generates a simple phyllotaxic arrangement of circles.

This application illustrates the notion of an integer’s factors, and of the related property of integers called primeness, or primality. An integer is called prime if it is the product of only one distinct pair of integers.

BMP EMF Grapher - drawing 2-D mathematical freeware with BMP, EMF, CSV export and CSV import. It draw graphics and exports them to the BMP, EMF, and CSV formats and imports CSV files to export to BMP or EMF format.
