Rcapture (version 1.1)

histpos: Possible Capture Histories

Description

histpos.t builds the matrix of observable capture histories in terms of captures and misses for a capture-recapture experiment with t capture occasions. histpos.0 builds the matrix of observable capture histories in terms of number of captures for each primary period of a robust design with vt capture occasions.

Usage

histpos.t(t)
histpos.0(vt)

Arguments

t
The number of capture occasions.
vt
A vector containing the numbers of capture occasions for each primary sampling period of a robust design. The length of this vector equals the number of primary sampling periods (noted $I$).

Value

  • histpos.t gives a $2^t-1$ by $t$ matrix with rows representing capture histories. This matrix contains only zeros and ones. histpos.0 gives a $(t_1+1)\times(t_2+1)\times \ldots \times(t_I+1)-1$ by $I$ matrix with rows representing possible capture histories in terms of number of captures. This matrix elements are integers between 0 and $t_i$ inclusively.
