Compute a criterion based on Credible Intervals (CI) to determine whether
the posterior t-distributions of groups should be considered different enough
to deserve further examination. Two groups are considered probably 'distinct'
if the Credible Interval of level CI_level of their respective
posterior t-distributions do not overlap.
identify_diff(posterior, CI_level = 0.05, nb_samples = 1000)A tibble, indicating which peptides and groups seem to be different
A tibble, typically coming from a posterior_mean()
function, containing the parameters of the multivariate posterior
t-distributions for the mean of the considered groups and draws for each
peptide.
A number, defining the order of quantile chosen to assess differences between groups.
A number (optional), indicating the
number of samples to draw from the posteriors for computing mean and
credible intervals . Only used if posterior is multivariate,
typically coming from a multi_posterior_mean() function.
