• Operation system:
  MS Windows 95/NT and higher.

• Version: 11.7 last modification at Aug. 26, 2005.

• Type: Shareware with 3 hours of free trial period.

• Main features of LeoStatistic software application:
  
  • Data
    • Import data series (tables) from: database (MS Access for example) table or by custom SQL request; text file; copy/paste from spreadsheet (MS Excel); get them from chart image or type in spreadsheet like data control.
    • Operate more then one data series (tables) at the same time.
    • Virtually unlimited^* number of records to present and analyze.
    • Recognition of  calendar mm/dd/yyyy data format transferring it into yyyy.yyyy to use for market (currencies, shares, commodities) time series trend analyzing.
    • Add and modify a parameters in data series by user defined formulas or simple incorporated schemes.
  • Visual presentation and statistical analysis:
    • Calculating matrix of correlations for all parameters in first data series and visually presenting them as a table of  x-y charts.
    • Building histograms of variable distributions comparing them with Student and Poisson probability densities. There is an option to calculate distributions conditioned to other parameters.
    • Visual presentation in form of X-Y chart of correlation between two variables plus an ability to implement a variety of curve fitting schemes for approximation to find best matching  formula.
    • Three dimensional histogram for distribution of two variables. There is also an option to present it as a color map.
    • Three dimensional, in perspective projection presentation of variable as a function of two arguments and multivariate approximation of it as a plane or parabola like surface.
    • Linear and parabolic multivariate regression of number of arguments.
    • Near neighbors method for multivariate estimation of value on the premise that closest in multidimensional space points have alike values.
    • Calculation of probability score for chosen variable (response) to be more then given value for defining a  pool of prospective customers.
  • Results.
    • Visualized data and abstract of statistical results are displayed on the screen in report-ready form. Detailed statistical formulas and coefficients are shown at the result panel.
    • User has ability to copy/paste screen chart as a bitmap picture into MS Office applications as well a content of result panel in the table format.
    • There is an option to instantly create a MS Word document with a result chart and text content of the result panel.
    • A calculation of value for the given set of arguments for active statistical scheme when available (few logical exclusions applied).
    • A modeling of the array of arguments is defined in text file on the base of active statistical scheme with the option to sort results and save in text file. This option can be used for prediction of data behavior including selection of most perspective candidates (consumers).
  • Interface.
    • Transparent and self-explanatory user interface conveniently located at control panel of application.
    • No more than three clicks are ever required to edit statistical schemes or presentation options.

*Programmable limitation on the number of records is 2³². (10¹⁰) Another limit of the software is time consumption and depends on the available memory and processor speed of the computer. For different statistical schemes times of calculations could be remarkable different. In general one can say that for less then thousand records any statistical schemes will perform practically instantly.
