histpos {Rcapture}R Documentation

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 (t1+1)*(t2+1)* ... *(tI+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 ti inclusively.

Note

The histpos.t function is called by descriptive, closedp, closedp.bc, closedp.Mtb, closedp.h, openp, Xomega.t, Xclosedp.

The histpos.0 function is called by Xomega.0 and robustd.0.
