StatXact 8- Software for small-sample categorical and nonparametric dataNew in StatXact 8 | System Requirements | Further Information
"The culmination of ten years of intense research and development, StatXact 8 is the most complete, up-to-date software package for exact nonparametric statistical inference on continuous or categorical data in the world. With StatXact we've covered every mainstream nonparametric procedure, using a full-fledged GUI implementation under Windows. We have provided at least one solution for every important nonparametric statistical problem involving either binary, categorical or continuous data. And, as is our trade-mark, every single one of these solutions is exact. That is, it remains valid for small, sparse and unbalanced data sets. All in all you can access over 80 exact procedures through the StatXact pull-down menus. In addition, we've provided the tools for you to construct your own exact procedures, or to combine two or more procedures in an optimal fashion through a suitable choice of scores. When it comes to handling small-sample data, no other statistical package can even come close to the power and scope of StatXact. Here are some highlights from the StatXact procedures:"
New Features in StatXact 8The Friedman Aligned Rank Test
Friedman's Aligned Rank Test serves as an alternative to the regular Friedman Test. The aligned rank test is a better
choice when the data have very few treatments and the blocks have different magnitudes of effect and scale.
The regular Friedman test is less sensitive for smaller number of treatments. This is due to the fact that in Friedman test,
the observations are ranked within a block. Thus the comparison is made among the responses within each block only.
The comparison of responses between blocks will not be meaningful as the blocks might have different magnitudes of effect and scale among themselves.
The blocks may be such that some may give consistently high, and others consistently low, responses.
