متن کاملPitfalls of statistical hypothesis testing: multiple testing.
The word " five " is missing from the third sentence of the fifth paragraph in the online answers to this Endgames article by Philip Sedgwick (BMJ 2014;349:g5310, doi:10.1136/bmj. g5310). The sentence should have read: " For example, the probability of a significant result when there are two, three, four, and five hypothesis tests is 0.
متن کاملStatistical Hypothesis Testing and Private Information∗
This paper provides a rationalization for using classical one-sided hypothesis tests for approving innovations, such as new drugs or treatment programs. I consider statistical testing as a strategy of the regulator in a game against informed proponents who can profit from the regulator’s acceptance decision even for ineffective innovations. Lower test size deters proponents from attempting cost...
متن کاملStatistical Hypothesis Testing in Positive Unlabelled Data
We propose a set of novel methodologies which enable valid statistical hypothesis testing when we have only positive and unlabelled (PU) examples. This type of problem, a special case of semi-supervised data, is common in text mining, bioinformatics, and computer vision. Focusing on a generalised likelihood ratio test, we have 3 key contributions: (1) a proof that assuming all unlabelled exampl...
متن کاملTesting statistical hypothesis on Random Trees
In this paper we address the problem of identifying differences between populations of trees. Besides the theoretical relevance of this problem, we are interested in testing if trees characterizing protein sequences from different families constitute samples of significantly different distributions. In this context, trees are obtained by modelling protein sequences as Variable Length Markov Cha...
