DATA-DERIVED ASSOCIATIONS ARE NOT TESTS OF THESE ASSOCIATIONS
Pediatrics, 1990...It is important to realize that comparisons of any subgroups within a randomized trial that are defined after randomization are no longer randomized comparisons. At best, such comparisons would have the characteristics of an observational study rather than a randomized trial, with all the attendant concerns about the control of confounding. At worst,

A Nonparametric Test for Association with Censored Data
Biometrics, 1978A nonparametric procedure is proposed for the problem of testing association between two continuous variables when one is subject to arbitrary censoring. The motivation for the procedure derives from our finding that Cox's likelihood procedure may not adequately control the size of the test.

Analysis of Genome-Wide Association Data
2016The last decade has seen substantial advances in the understanding of the genetics of complex traits and disease. This has been largely driven by genome-wide association studies (GWAS), which have identified thousands of genetic loci associated with these traits and disease.

Massively parallel bit-serial SIMD computers such as the MMP* with 16K processors and the Connection Machinet† with 64K processors eliminate the need for time-sharing a single central processing unit with a multitude of data elements, thus avoiding the classic memory—CPU bottleneck.
