The Most Popular Exact Statistics Analysis Software

New features and innovative statistical methodologies continue to advance Cytel's highly-regarded exact statistics software.

What is StatXact® for?

Statisticians and investigators access the widest offering of validated exact statistics tests and methodologies. The environment is easy to understand or customize. The results are fast and accurate.

What sets it apart?

Other statistical applications often rely on large-scale assumptions for inferences, risking incorrect conclusions from data sets not normally distributed. With StatXact, Cytel's own powerful algorithms make exact inferences by permuting the actually observed data, eliminating the need for distributional assumptions.
