Randomization of presence-absence data matrices with fixed row and column totals is an important tool in ecological research wherever the significance of data-based statistics (e.g., species ...

DOE Randomized Algorithms for Combinatorial Scientific ComputingPlease see the full solicitation for complete information about the funding opportunity. Below is a summary assembled by the Research & ...

This paper presents a modular framework for constructing randomized algorithms that compute partial matrix decompositions. These methods use random sampling to identify a subspace that captures most ...

The algorithm translates this preliminary evidence on the basis of PFS data into unbalanced randomization probabilities that may vary across biomarker groups. We previously presented simulation ...

Randomization Techniques (60 minutes): In this workshop, the rationale behind randomized experiments will be explained. Descriptions of commonly utilized randomization algorithms will be presented, ...

Treatment arms may drop because of low probability of treatment impact on overall survival, and new arms may be added. Detailed information on the statistical model and randomization algorithm is ...
