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.
