WebBy default, the p-value is determined by comparing the t-statistic of the observed data against a theoretical t-distribution. When 1 < permutations < binom (n, k), where k is the number of observations in a, n is the total number of observations in a and b, and binom (n, k) is the binomial coefficient ( n choose k ), Webpval = binom_test(observed_successes, sample_size, expected_probability_of_success, alternative = 'greater') Converting P-Values P-values are probabilities. Translating from a probability into a significant or not significant result involves setting a significance threshold between 0 and 1.
