Computes the fraction of simulated neurons with Poisson spike counts which are rejected by a sequence of tests. First a t-test for a difference from baseline for any category, followed by an ANOVA of an effect of category on the cells found to be significant in the first test.
1 2 | compRejectionFraction(bkgLevel, respLevel, numCats, pretestP, anovaP, showProgress =
FALSE, numTrialsPerCat = 10, numCells = 1000)
|
bkgLevel |
Average firing rate for background counts. |
respLevel |
Average firing rate for response counts. |
numCats |
Number of categories to test for a response in. |
pretestP |
p-value to use in first t-test for a difference from baseline. |
anovaP |
p-value to use in second ANOVA testing for an effect of category on the responses. |
showProgress |
TRUE if should list cell number as calculating. Default is FALSE. |
numTrialsPerCat |
Number of trials, with background and response counts, in each category. Default is 10. |
numCells |
Number of cells to simulate. Default is 1000. |
If the first and second tests were operating independently, the rejectionFrac would remain constant and equal to the anovaP value for all exclusion fractions.
exclusionFrac |
Fraction of cells which were not rejected by the first t-test; thus fraction of those ignored for the second test. |
rejectionFrac |
Fraction of cells rejected by the first test which were rejected by the second test. |
Both the t-test and the ANOVA assume a normal distribution of the counts.
