SYSTAT 12
Introduction
SYSTAT is a powerful statistics package that has every statistical procedure you need to carry out efficient statistical analysis of your data. With SYSTAT, analysing and presenting environmental data requires less effort than with a business orientated statistical software system.
- SYSTAT is used by environmental researchers because of its statistics, data analysis, visualisation and technical graphing capability.
- SYSTAT provides you with features from the most elementary descriptive statistics to advanced statistical methods based on proven statistical algorithms.
- SYSTAT also has the most comprehensive range of scientific and technical graphing options of any desktop statistics package.
- SYSTAT is available at the academic price for hospitals.
If you are a novice statistical user, you can work with SYSTAT's friendly and simple menu-dialog. If you are a statistically-savvy user, you might prefer to use SYSTAT's intuitive command language and analyse your data swiftly and with ease.
In either case, you can exploit SYSTAT's staggering range of powerful techniques to analyse many types of data to answer many types of questions. You can carry out very comprehensive analysis of univariate and multivariate data based on linear, general linear, and mixed linear models. You can carry out different types of robust regression analysis when your data are not suitable for conventional multiple regression analysis. You can also compute partial least-squares regression. You can design experiments, carry out power analysis, do probability calculations on a whole lot of distributions and fit them to data. You can perform matrix computations. Anything else you may need---Time Series, Survival Analysis, Response Surface Optimisation, Spatial Statistics, Test Item Analysis, Cluster Analysis, Classification and Regression Trees, Correspondence Analysis, Multidimensional Scaling, Conjoint Analysis, Quality Analysis, Path Analysis, etc., etc.---SYSTAT has them all.
Accomplish your Simulation Tasks with the Monte Carlo Feature
Use the powerful Mersenne-Twister random number generator for your bootstrap and simulation tasks. Exploit SYSTAT's random sample generation from as many as 33 univariate and multivariate, discrete and continuous distributions. Use Rejection and Adaptive Rejection Sampling procedures for sampling from more complicated distributions. Get help from SYSTAT for your Bayesian computations with the generic Markov chain Monte Carlo (Metropolis-Hastings and Gibbs Sampler) algorithms and Monte carlo integration thereof.
Visualise Your Data With More Graphing Capabilities
SYSTAT offers a large number of scientific and technical graphing options and a great deal of interactivity for a deskktop statistics package. Compare subgroups, overlay charts, transform coordinates, add geographic projections, change colors, symbols and more to create insightful presentations. Change graph locations, point-and-click to alter axis labels, scales, colors and symbols. Create unique graphs that bring out the true meaning in your data with advanced chart options including normal and kernel densities, multiplots, maps, Voronoi tessellations, function plots, contours, scatterplot matrices with 20 diagonal density choices and 126 non-parametric smoothing options, just to name a few. Speed up your analysis by rotating your 3-D graphs to visually determine the perfect power or log transformation to normalise your data using the Dynamic Explorer. Create insightful presentations with advanced chart types such as maps, multiplots and kernel densities. Speed up your analysis with SYSTAT's interactive graphic tools. Simply point-and-click to perfect your graph's appearance.
Get Meaningful Results With Less Effort
Tired of extravagant user interfaces slowing you down? Stalled by difficult programming languages? SYSTAT's intuitive Windows interface and flexible command language are designed to make your research more efficient. Easily locate advanced options through clear, comprehensive dialogs. Type commands directly into SYSTAT's interactive command window to fly through your analyses. Quickly navigate through detailed results using the browser-style Output Organiser. Make dramatic changes in your analysis with a few keystrokes. SYSTAT's command language is interactive, powerful and easy to learn. Write commands using plain English with minimal, forgiving syntax that's consistent across all modules. Instantly visualise your results with SYSTAT's Quickgraphs produced automatically by most statistical procedures to provide immediate and intuitive feedback. Use the variety of online help available at your fingertips to speed up your work.
Completely Automate Your Analysis
Speed up your analyses with SYSTAT's flexible command language providing complete coverage of menu-based functionality. Quickly run the same analysis on different data using token variables in command templates. Each time you run the command file, you'll be prompted to select a variable to replace the token. Create command files in no time. Execute functions using the menus and dialog selections while the command log tracks your steps. Simply save the command log script to re-run your analysis. Use the command files of over 500 examples available in the SYSTAT directory to carry out similar analysis on your data sets. Track and report your statistical methodology to monitoring agencies using the command log. Create compelling reports by combining formatted statistical output with publication-quality graphs in SYSTAT's rich text output window then automate them.
