What is different about the q-value and local FDR?

    The q-value can be interpreted as the false discovery rate (FDR): the proportion of false positives among all positive results.

    The q-value can be interpreted as the false discovery rate (FDR): the proportion of false positives among all positive results.

False Discovery Rate (FDR), adjusted p-value, and Q-values

    In statistics, the false discovery rate (FDR) is a method of conceptualizing the rate of type I errors in null hypothesis testing when conducting multiple comparisons.
q-value significance The pFDR and the q-value were introduced by John D. Storey in 2002 in order to improve upon a limitation of the FDR, namely that the FDR is not defined when.
q-value fdr The false discovery rate (FDR) is then simply the following: [1] = = [], where [] is the expected value of.
q-value cutoff q-value is a widely used statistical method for estimating false discovery rate (FDR), which is a conventional significance measure in the.

  • A q-value threshold of yields a FDR of 5% among all features called significant.

    Statistical hypothesis testing measure

    For other uses, see Q value.

    In statistical hypothesis testing, specifically multiple hypothesis testing, the q-value in the Storey procedure provides a means to control the positive false discovery rate (pFDR).[1] Just as the p-value gives the expected false positive rate obtained by rejecting the null hypothesis for any result with an equal or smaller p-value, the q-value gives the expected pFDR obtained by rejecting the null hypothesis for any result with an equal or smaller q-value.[2]

    History

    In statistics, testing multiple hypotheses simultaneously using methods appropriate for testing single hypotheses tends to yield many false positives: the so-called multiple comparisons problem.[3] For example, assume that one were to test 1, null hypotheses, all of which are true, and (as is conventional in single hypothesis testing) to reject null hypotheses with a significa

    • P-values, False Discovery Rate (FDR) and q-values - Nonlinear

      Q-value: Adjusted p-value that accounts for multiple comparisons, controlling FDR. FDR: A rate, not a single value, controlling the proportion of false positives among all significant.

  • The q-value of a test measures the proportion of false positives incurred (called the false discovery rate) when that particular test is called significant.

  • An FDR adjusted p-value (or q-value) of implies that 5% of significant tests will result in false positives.
