StatXact 10: 150 tests and procedures for exact inference

Exact p-values are often considered the gold-standard for measuring the strength of a statistical finding. However, computing p-values while evaluating large or unbalanced data sets, can raise an assortment of challenges for statisticians.

StatXact offers an expansive toolkit of non-parametric exact and Monte Carlo methods for accurate hypothesis testing. Its range of application extends across the natural and social sciences, and has contributed to decisive findings in economics, public health, law and the brain sciences.  

The advantages of StatXact

StatXact offers more tests and procedures for exact inference and power analysis than any other software package on the market. Fast and accurate inferences are compiled on an easy-to-use interface, drawing on complex algorithms created by Cytel’s team of statistical experts.

Benefits

   Empower

Play a more strategic role in your organization: Perform fast and accurate hypothesis-testing that is responsive to an array of trial needs. Obtain reliable results for smaller sample sizes, allowing for timely and cost-effective trials. Redirect time, attention and critical resources to other vital aspects of study success.

   Assess

Access StatXact’s selection of exact and Monte Carlos tests to increase the statistical power of trial results. Unnecessary risks associated with conventional (asymptotic) testing are curtailed using performance software that is fast and accurate.

   Share

StatXact simplifies tests that normally require complex calculation. Findings that should be difficult to compute are easy to identify and communicate.


   Trust

StatXact has harnessed the immense power of Cytel’s nonparametric and exact inference methods to make enduring contributions to the fields of population health, medical and clinical studies, epidemiology, economics, energy,finance, legal studies, natural sciences, geography and the brain sciences. StatXact has received acclaim from both industry and academia for its high quality performance of complex calculations.

Features

   The Toolkit:

Not only does StatXact provide more tests and procedures for exact inference and power analysis than any other software currently on the market, but many of these complex tests are only available to StatXact users. These exclusive features include exact tests for correlated two samples data, exact power and sample size computations for binomial and multinomial data, and exact tests for equivalence and non-inferiority of paired and independent binomial data.

   Exact Tests for Continuous Data:

StatXact features a range of exact and Monte Carlo tests for one-sample, two-sample and k-sample data (independent and blocked).

   Exact Tests for Categorical Data:

StatXact performs exact tests for both independent and correlated categorical data. It can compute tests for stratified Poisson samples, and is the only product on the market that delivers sample size and power calculations for binomial and multinomial distributions.

   New Developments:

Statisticians at Cytel are continuously developing new algorithms that offer users even more complex methods of exact-testing. Recent additions include: stratified Wilcoxon Signed Rank test utilizing case data on paired samples, p-values for the test of trend in multiple outcomes, and confidence intervals based on tests using the mid-p values.
