Creates a lambda of species counts (for use in a Poisson draw) based on explanatory factors. The levels are calculated additively with a fylke effect, a kommune effect, plus a random part (sigma) that determines the intra-kommune variation among grid cells. This is intended to fill a "map" with values of occurrences, and expects columns named fylke and kommune.
