Summary:
-
Name: LeoDataAnalysis.
-
Operation system: MS Windows.
-
Version: 3.1.
-
Type: Freeware without limitations.
-
Installation: press button to go to
installation page
for obtaining free executable LeoDataAnalysis.
-
Codes: Complete code project in MS Visual Studio C++ is available to
purchase for learning, modification or implementing of the state of art algorithms
and functions at
LeoDataAnalysis project page.
-
Main features:
-
Import Data Series:
-
Copy/paste from MS Excel or other table like sources.
-
Read text file.
-
Analyze image manually or automatically and import data in numerical form.
-
Read from MS Access database.
-
Data Modification:
-
Ability to analyze more then one data series (tables) simultaneously.
-
Modify values of parameters in data series by user defined formulas
or by incorporated simple schemes.
-
Purge data outside defined ranges.
-
Visualization of data and statistical analysis:
-
Calculating matrix of correlations for all parameters in data series
and visually presenting them as a table of x-y charts.
-
Building histograms of variable distributions comparing them
with Student, Erlang and Poisson probability densities. There
is an option to calculate distributions conditioned to other
parameters as well a probability that selected data is not random
subset. The state of art algorithm permits automatically find conditions
corresponded to most non-incidental subset of data.
-
X-Y chart of two variables with an ability to implement a variety
of curve fitting schemes:
like least square approximation, fit wit custom formula, harmonic
analysis and others.
-
Distribution of two variables presents as three dimensional histogram
or of iso-surfaced color map.
-
A value as function of two parameters are presented in form perspective
projection on the screen of its three dimensional coordinates
with ability to change user point of view.
-
Linear and parabolic multivariate regression more then two arguments.
-
Near neighbors method for multivariate estimation of value on the premise
that closest in multidimensional space points have alike values.
-
Local search in multidimensional space best fitting coefficients
for user defined formula of two or more arguments.
-
Calculation of probability (score) for chosen variable (considered
as a response) to be more then given value for defining the pool
of prospective customers in market research and followed advertising campaign.
-
Results.
-
There is an option to instantly create a MS Word document or
HTML page with a result chart and results of statistical analysis.
-
A calculation of value for the given set of arguments for active
statistical scheme when available (few logical exclusions applied).
-
Usage of active statistical scheme to produce fitting values
for array of arguments contained in text file. There is an option
to sort results and save them as a text file that can be used
for prediction including selection of most perspective leads (consumers).

Results user interface of LeoDataAnalysis. 
With help of controls in "Results" tab in LeoDataAnalysis user can export statistical results and visual presentation of data to report.
Statistics user interface in LeoDataAnalysis 
Statistics tab of LeoDataAnalysis has set of controls to chose available conditions of statistical schemes.
Data view user interface in LeoDataAnalysis. 
There are XY-chart and 3D styles of changing view in LeoDataAnalysis.
Chart area decoration user interface on LeoDataAnalysis. 
There are options to provide and modify title and axis legends in LeoDataAnalysis.
Import data from outside sorce 
Data series can be imported into LeoDataAnalysis from various outsidesources: pasted from clipboard, read from text file, analyzing chart like imagefile, from MS Access database file; manually typing into data editor dialog orinserting by formula or incorporated method.
Chart presentation user interface of LeoDataAnalysis 
Chart presentation user interface of LeoDataAnalysis permits to edit color and thickness of border for visualization area.
Data editing in LeoDataAnalysis. 
LeoDataAnalysis permits seamlessly editing data like adding additional parameter, arithmetic progression or by formula, filter outside range and so on, often just by few mouse clicks.
Data structure organization inside LeoDataAnalysis. 
Data structure organization inside LeoDataAnalysis cab be described as array of tables with named columns and numerical values. These tables are analogue to series of reports about experiments made different research teams.
Calculator interface for extrapolation and interpolation. 
For active statistical scheme LeoDataAnalysis offers possibility to calculate data for given by user set of arguments.
