What is Statxact?

StatXact 12 features over 160 tests and procedures for accurate inference

StatXact 12 provides statisticians in social and natural science disciplines with the world's most comprehensive toolkit for accurate inference and power analysis. Offering more than 160 tests and procedures, the StatXact suite has transformed the complex algorithms of modern statistical analysis into a validated software package with a user-friendly interface.

The advantages of StatXact 12

StatXact offers more testing and procedures for accurate inference and energy analysis than any other software package on the market. Fast and accurate inferences are compiled into an easy-to-use interface, based on complex algorithms created by Cytel's team of statistics experts.

Our experts are constantly developing new types of exact tests, expanding the selection of calculations available to our users. Many of these methods are available only to StatXact users and have received praise for their performance in both the industry and academia.

The benefits of StatXact 12

Empowerment

Play a more strategic role in your organization: perform fast and accurate hypothesis testing that meets a variety of testing needs. Get reliable results for smaller samples, enabling timely and economical testing. Redirect time, attention, and critical resources to other vital aspects of the study's success.

Trust in

StatXact harnessed the immense power of Cytel's nonparametric and accurate inference methods to make lasting contributions to the fields in the natural and social sciences, receiving praise from industry and academia for its high-quality performance in complex calculations.

Share

StatXact simplifies tests that typically require complex calculations. Discoveries that should be difficult to calculate are easy to identify and communicate.

Evaluate

Access statxact's exact test selection and Monte Carlos to increase the statistical power of test results. The unnecessary risks associated with conventional (asytotic) testing are reduced using fast and accurate performance software.

StatXact 12 features

The Toolkit

StatXact not only provides more testing and procedures for accurate and power analysis than any other software currently on the market, but many of these complex tests are only available to StatXact users. These unique features include accurate tests for data from two correlated samples, accurate power and sample size calculations for binomial and multinomial data, and exact tests for equivalence and non-inferiority of paired and independent binomial data. StatXact and LogXact users can also request an exact crossover module for a 2x2 cross-evaluation.

New developments

Cytel statisticians are continually developing new algorithms that offer users even more sophisticated methods of accurate testing. Innovations in StatXact 12 include:

  • Multi-endpoint procedure with gatekeeping
  • Pesarin-Salmaso nonparametric combination test for multivariate data
  • Super-superiority test for two independent binomials
  • New asynotic confidence interval methods for two independent binomials
  • Unconditional test of the odds ratio for two independent binomials
  • Estimation of parameters for stratified binomials of 2 samples
  • Accurate analysis of negative binomal data from 1 and 2 samples
  • Accurate calculation of power and sample size for negative binomal data of 1 and 2 samples
  • Accurate calculation of power and sample size for Poisson data of 1 and 2 samples

Accurate testing for continuous data

StatXact features a variety of exact monte carlo tests for data from one sample, two samples, and k samples (independent and blocked).

Accurate tests for categorical data

StatXact runs exact tests for independent and correlated categorical data. It can calculate tests for stratified Poisson samples and is the only product on the market that provides sample size and power calculations for binomial and multinomial distributions. StatXact 12 provides additional nonparametric inference tests for categorical data and adds existing coefficient options for correlated categorical data.
