Description of frequencies
Description of the rows of a contingency table or of groups of rows of a contingency table
descfreq(donnee, by.quali = NULL, proba = 0.05)
donnee |
a data frame corresponding to a contingency table (quantitative data) |
by.quali |
a factor used to merge the data from different rows of the contingency table; by default NULL and each row is characterized |
proba |
the significance threshold considered to characterized the category (by default 0.05) |
Returns a list with the characterization of each rows or each group of the by.quali
. A test corresponding to the hypergeometric distribution is performed and the probability to observe a more extreme value than the one observed is calculated. For each row (or category), each of the columns characterising the row are sorted in ascending order of p-value.
