get.significance | R Documentation |
Obtains the TDS significance proportion based on the number of observations and chance, as proposed by Pineau et al. (2009; Eq. 1).
get.significance(chance, n, alpha = 0.05)
chance |
chance proportion; see |
n |
number of observations. |
alpha |
significance level for binomial test of 2 independent proportions (based on normal approximation; see: Pineau et al., 2009, Eq. 1) |
The TDS significance level proposed by Pineau et al. (2009, Eq. 1) provides a simple and widely used heuristic approach for contextualizing observed dominance rates, but should not be used for statistical inference.
