MEMM implements a Bayesian statistic method first presented in Klein et al. (2008). It estimates the pollen dispersal function and the variance in male fecundity on the basis of spatial information (positions of sampled plants, positions of all putative fathers in the study plot) and genetic information (genotypes of the sampled plants, putative fathers and sampled seeds).
Klein et al. (2011) investigates the performance of the method on simulated datasets and illustrate how neglecting the random component in male fecundity can lead to erroneous conclusions.

Version v2.0

Version 2.0 changes :
- Parameter file change to xml format.

What's new in version v1.1

·      A bug in version V1.0 was fixed. This bug was leading to excessively low values of the shape parameter b and excessively high values of the dispersal distance d and of the variance of fecundity dobs/de.
·      The gamma distribution is now implemented
·      In is now possibility to define weighting variables (Be careful, Parameters.txt needs one more information even when not using weighting variables)
·      It is no more necessary to define a useless file name when allelic frequencies are computed from adult individuals.
·      The CI for the parameter 1 was corrected.
