StatCalc
This very user-friendly desktop tool simplifies common statistical calculations and also allows quick analysis of raw data whether you enter it yourself, use a spreadsheet, or maintain a database. Copy data from spreadsheets, database tables, import text files, or enter data directly into the spreadsheetﾠto quickly produce basic statistical analyses.
Survey Power
Create and analyze surveys, questionnaires, and opinion polls. Print blank surveys, record survey responses, perform complete frequency, thematic maps, cross-tabulation, and statistical analyses of the survey responses. Professional version includes web survey creation with validation, email data entry, multi-color charting, and 12 data export file formats including Microsoft Excel. Multi-demographic analysis also supported.
Unit Converter for Excel
Unit Converter for Excel is an addin for the Microsoft Excel to perform
various conversions between many types of measurement units. The units are
grouped in the following categories: Dimensions and capacity, Energy and
power, Mechanics, Hydraulics, Heat, Electricity, Magnetism, Light and sound,
Radiation.
VIGps
- you can show a current GPS data (Speed, Direction, Longitude, Latitude, Time, Date, Height);
- you can open any of scanned maps (in a "bmp" or "dib" format);
- you can calibrate the scanned maps yourself by two calibration points only (left-top and right-bottom);
- calibrations are stored automatically for every map, you do not need to calibrate a map next time;
- you can see your route line at the map;
VIGraph
VIGraph
It draws a diagramms from your txt-data files.
It scales your diagramms automatically or manually.
Simply make a txt or csv (ASCII) file like that:
Dow Jones
Date; Open; High; Low; Close
4.14.2005; 10403.71; 10457.06; 10248.23; 10278.75
4.15.2005; 10276.61; 10311.26; 10059.36; 10087.51
Run VIGraph and open that file. You will get a diagramm with 4 colored lines (for Open; High; Low; Close).
VIMeteo
Real-time weather data from 7000 stations all around the world.
History of weather data for the past 1 - 60 hours.
USA or European style
Data output ( txt-file) for every opened station.
