ABC_P2_pois {ABCp2} | R Documentation |
This function fits offspring data to the Poisson distribution and estimates P2 based on that distribution and the specificed priors.
ABC_P2_pois(n, ObsMean, L_Lo, L_Hi, delta, iter)
n |
the number of observations. |
ObsMean |
the observed mean number of offspring sired by the second male. |
L_Lo |
minimum lambda value for the distribution. |
L_Hi |
maximum lambda value for the distribution. |
delta |
maximum allowed difference between the estimated mean and observed mean number of offspring produced by the second male. |
iter |
number of iterations used to build the posterior. |
posterior |
Posterior distribution of P2 values. |
Lambda |
Vector of values for the lambda parameter. |
