eq02buildW1Mat: Equation 2: Build winter survival matrix (S.w)

In brouwern/FACavian: An R implementation and extension of full-annual cycle (FAC) model of Runge & Marra *2005)

Equation 2: Build winter survival matrix (S.w)

Description

This function produces a diagonal matrix of survival (S.) values. in winter (S.w) for males (.m) and females (.f) in both good (._g) and poor (._p) habitat

Usage

eq02buildW1Mat(S.w.mg = 0.8, S.w.mp = 0.8, S.w.fg = 0.8, S.w.fp = 0.8)

Arguments

S.w.mg	Survival (S) in the winter (w) of males (m) in good (g) habitat
S.w.mp	Winter survival of males in poor (p) habitat.
S.w.fg	Winter survival of female birds (f) in good habitat
S.w.fp	Winter survival of females in poor habitat

Details

TODO(): I call the matrix returned by the function S.w; why not W1?

Value

S.w (W1) matrix of winter (w) survival probabilities by sex and winter habitat
