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.
Our experts are constantly developing new types of exact tests, broadening the selection of calculations available to our users. Many of these methods are only available to StatXact users, and have received acclaim for their performance from both industry and academia.
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.
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 across the natural and social sciences, receiving acclaim from both industry and academia for its high quality performance of complex calculations.
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.
The Toolkit: Not only does StatXact provide more tests and procedures for exact 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. Users of StatXact and LogXact can also request an Exact crossover module for a 2x2 crossover trial,
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).
New Developments: Statisticians at Cytel are continuously developing new algorithms that offer users even more complex methods of exact-testing. Recent additions include: Blaker's exact methods; the introduction of Bayesian confidence intervals; parallel processing for power, sample size, and analyses; additional nonparametric inference tests for categorical data; new coefficient options for correlated categorical data; 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.
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.StatXact 11 provides additional nonparametric inference tests for categorical data, and adds to existing coefficient options for correlated categorical data.
