Example sentences for: two-sample

How can you use “two-sample” in a sentence? Here are some example sentences to help you improve your vocabulary:

The SAM procedure computes a two-sample T-statistic (for example for normal vs AIS cell lines) for the normalized log ratios of gene-expression levels for each gene.
For simplicity, let σ 1 2= σ 2 2= σ 2. Suppose we use two-sample t-test to test H 0 : μ 1 = μ 2 against H a : μ 1 <μ 2 . Without pooling, the t statistic follows the central t distribution f ( t, df 1 ) with df 1 = 2( n - 1) under H 0 ; while under H a , it follows a non-central t distribution with df 1 and non-centrality parameter , which is inversely related to the standard deviation σ.
On the basis of the above observation, we calculate the following two-sample t -statistic for each gene as its measure of possible differential expression:
Once we obtain an estimate of the null distribution f 0 , we can determine the cut-off point of the rejection region for testing H 0 . In general, as for a two-sample test, the rejection region can be selected in the tails of f 0 because, under the null hypothesis, Z
For a two-sample t test, this means the true difference between the means is one half of the common standard deviation.
