Conditional versus Unconditional Exact Tests for Comparing Two Binomials
نویسنده
چکیده
There are two fundamentally different exact tests for comparing the equality of two binomial probabilities – Fisher’s exact test (Fisher, 1925), and Barnard’s exact test (Barnard, 1945). Fisher’s exact test (Fisher, 1925) is the more popular of the two. In fact, Fisher was bitterly critical of Barnard’s proposal for esoteric reasons that we will not go into here. Notwithstanding Fisher’s reservations, both tests are available in StatXact.

Exact unconditional tests for a 2 x 2 matched-pairs design.
The problem of comparing two proportions in a 2 x 2 matched-pairs design with binary responses is considered. We consider one-sided null and alternative hypotheses. The problem has two nuisance parameters. Using the monotonicity of the multinomial distribution, four exact unconditional tests based on p-values are proposed by reducing the dimension of the nuisance parameter space from two to one...
متن کاملA cautionary note on exact unconditional inference for a difference between two independent binomial proportions.
Fisher's exact test for comparing response proportions in a randomized experiment can be overly conservative when the group sizes are small or when the response proportions are close to zero or one. This is primarily because the null distribution of the test statistic becomes too discrete, a partial consequence of the inference being conditional on the total number of responders. Accordingly, e...
متن کاملTests for the homogeneity of two binomial proportions in extremely unbalanced 2 x 2 contingency tables.
Asymptotic tests such as the Pearson chi-square test are unreliable for testing the homogeneity of two binomial probabilities in extremely unbalanced cases. Two exact tests (conditional and unconditional) are available as alternatives and can be implemented easily in StatXact 6.0. In equal sample cases it is well known that the unconditional exact test is more powerful than the conditional exac...
متن کاملPower Comparison of Exact Unconditional Tests for Comparing Two Binomial Proportions
The powers of six exact, unconditional tests for comparing two binomial proportions are studied. Total sample sizes range from 20 to 100 with balanced and imbalanced designs included. Some previously proposed tests are found to have poor power for imbalanced designs. Two new tests, confidence interval modifications of Boschloo’s and Suissa and Shuster’s tests, are found to have the best powers....
متن کاملPowerful Exact Unconditional Tests for Agreement between Two Raters with Binary Endpoints
Asymptotic and exact conditional approaches have often been used for testing agreement between two raters with binary outcomes. The exact conditional approach is guaranteed to respect the test size as compared to the traditionally used asymptotic approach based on the standardized Cohen's kappa coefficient. An alternative to the conditional approach is an unconditional strategy which relaxes th...
