No need to carry a mainframe computer to perform a complex statistical analysis when you visit a remote lab. Even a notebook computer is no longer necessary with StatPlus Portable 2007. You only need a light and extremely compact USB flash drive. Plug it into any PC in the lab, and get your customary workplace in a matter of minutes!
Have the full power of a professionally developed and precise statistical package always with you. Perform a statistical analysis on-the-fly without carrying a powerful, bulky computer with you all the time. This portable version is able to run from a flash memory stick, and does not require installation to the host PC.
Despite its light designation, StatPlus Portable 2007 is a fully featured, powerful data analysis product. It performs all types of analysis, from very basics to complex procedures such as GLM ANOVA, non-parametric and regression analysis, Probit analysis and Latin squares analysis.
Get consistent, repeatable, ISO compliant results every time you perform an analysis. StatPlus is fully standardized and complies with the strict ISO standards such as ISO2602:1980, ISO 2854:1976, and ISO 3207:1975. Import and export to popular products such as Microsoft Excel and StatSoft Statistica makes StatPlus even more compatible.
Statistical analysis tools such as StatPlus are not for everyone. Heavy-duty packages carry high costs and steep learning curves. With StatPlus you can forget about the learning curve thanks to its intuitive, spreadsheet-like user interface that is as easy to use as MS Excel.
Are you working in a lab or studying for your PhD? With its highly affordable price tag and available student and academic discounts, StatPlus Portable 2007 makes a perfect tool for industrial workers as well as university students and teachers.

BioStat - user-friendly biology and medicine oriented statistical software. With BioStat 2007, one gets a robust suite of statistics tools and graphical analysis methods that are easily accessed though a simple and straightforward interface. While BioStat 2007 is a “heavy-duty” biology and medicine oriented professional statistical analysis tool, the interface is so simple that even people who have no knowledge of statistics are capable of processing data, provided they know how to use PC and clear instructions are given. This frees up intellectual resources for analyzing the results, rather than agonizing over who and how processed the data, and if any mistakes were made in the process.

EasyFit allows to easily and quickly select the probability distribution which best fits to data, reducing your analysis times by 70-95% over manual methods. It includes numerous features designed to save you time, prevent analysis errors, and help you make better decisions.

An integrated environment provided by EasyFit includes data management, analysis, and reporting capabilities ensuring the high quality of your projects. It is very easy to learn and use - requires only a basic knowledge of statistics, so you can master it in a day or two.

The key feature of EasyFit is the ability to automatically fit over 40 distributions to sample data. Advanced users can also apply the flexible manual fitting capability. After the distributions are fitted, they are ranked accordingly to the goodness of fit tests (Kolmogorov-Smirnov, Anderson-Darling, Chi-Squared) allowing you to select the best model.

A variety of high-quality graphs (probability density, cumulative probability, survival, hazard, P-P plot etc.) can be used to visually compare the fitted distributions and make sure you have chosen the most valid one. Finally, you can apply the integrated StatAssist tool to get a comprehensive information (moments, quantiles, probabilities) on the selected distribution.

Additional features include hypertext reports, random number generator, and visual distribution gallery.
