exact test उदाहरण वाक्य

उदाहरण वाक्य

1. but Fisher's exact test isn't really relevant to this form of the data, if I understand the OP's question.
2. For many cases of interest this approximation is accurate and Fisher in 1950 derived an exact test for it.
3. The Agriculture Department has said any positive results from the rapid tests will be verified by more exact tests.
4. The exact test pressure tolerated before rotation is highly dependent on connecting rod angle, bore, compression of other cylinders, and friction.
5. Until last year, there had been no exact test to detect the use of EPO . Race organizers tested a rider's blood.
6. On the second analysis, the data are suitable for Pearson's chi squared, but the program goes ahead and calculates Fisher's exact test-statistic.
7. In practice this becomes computationally onerous as k and N increase so it is probably only worth using exact tests for small samples.
8. Similarly, in analyses of contingency tables, the chi-squared approximation will be poor for small sample size, and it is preferable to use Fisher's exact test.
9. In the vast majority of applications this assumption will not be met, and Fisher's exact test will be over conservative and not have correct coverage.
10. Exact tests, and asymptotic tests based on the Fisher transformation can be applied if the data are approximately normally distributed, but may be misleading otherwise.
