createOccNorm: createOccNorm

In NINAnor/SurveyPower: Functions for calculating power of survey design

Description

Creates a probability of species occurrence 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.

Usage

createOccNorm(map, intercept = 0.5, sigmaFylke = 0.1,
  sigmaKommune = 0.1, sigmaGrid = 0, sigmaSurvey = 0,
  sigmaFylkeTrend = 0, sigmaKommuneTrend = 0, artypeEff = c(Bebygd =
  0, Samferdsel = 0, `Fulldyrka jord` = 0, `Overflatedyrka jord` = 0,
  Innmarksbeite = 0, Skog = 0, `Åpen fastmark` = 0, Myr = 0, Isbre = 0,
  Ferskvann = 0, Hav = 0, `Ikke kartlagt` = 0), artypeTrend = c(Bebygd =
  0, Samferdsel = 0, `Fulldyrka jord` = 0, `Overflatedyrka jord` = 0,
  Innmarksbeite = 0, Skog = 0, `Åpen fastmark` = 0, Myr = 0, Isbre = 0,
  Ferskvann = 0, Hav = 0, `Ikke kartlagt` = 0), nYears = 5,
  interceptTrend = -0.05, sdInterceptTrend = 0, sortFylke = T,
  sortKommune = T, sortGrid = T)

Arguments

sigmaFylke	Standard deviance of fylkes
formula	Not yet implemented
sigmaFylke	Standard deviance of kommunes.
sigmaFylke	Standard deviance of grids.
