• Name: LeoDataAnalysis.
• Operation system: MS Windows.
• Version: 1.2.
• Type: Freeware with limitations. Price for license to free of limitations version starts from \$9.95 USD for one day.
• Installation: press button to go to
• Main features:

• Import Data Series:

• Copy/paste from MS Excel or other table like sources.
• 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).
