例句與造句

1. A common strategy is to approximate the null distribution with a scaled random variable.
2. In cases where the tests are not independent, the null distribution of " X " 2 is more complicated.
3. For all such functionals, their null distribution ( under the hypothetical F ) does not depend on F, and can be calculated once and then used to test any F.
4. A recent paper describes both the calculation of a sample based version of this measure for use as a test statistic, and calculation of the null distribution of this test statistic.
5. While weighted versions of Fisher's statistic can be derived, the null distribution becomes a weighted sum of independent chi-squared statistics, which is less convenient to work with.
6. It's difficult to find null distribution in a sentence. 用null distribution造句挺難的
7. This distribution often arises in the power analysis of statistical tests in which the null distribution is ( perhaps asymptotically ) a chi-squared distribution; important examples of such tests are the likelihood ratio tests.
8. The null distribution of this statistic is calculated under the null hypothesis that the sample is drawn from the reference distribution ( in the one-sample case ) or that the samples are drawn from the same distribution ( in the two-sample case ).
9. A two-tailed test may still be used but it will be less powerful than a one-tailed test because the rejection region for a one-tailed test is concentrated on one end of the null distribution and is twice the size ( 5 % vs . 2.5 % ) of each rejection region for a two-tailed test.
10. If such data sets ( typically 1, 000 or more ) are analyzed with the same statistical procedure that is used to analyze a real data set, then results for the simulated data sets can be used to create phylogenetically correct ( or " PC " ) null distributions of the test statistic ( e . g ., a correlation coefficient, t, F ).
