Open Robust Design Multi-State Model for Live Recaptures<\/b><\/span><\/p>\n

The muti-state data type<\/a> was extended to have a robust design<\/a> by Kendall and Bjorkland (2001)<\/a>.\u00a0 Each primary session is considered to be open, allowing animals to immigrate and emigrate from the study area.\u00a0 However, an animal’s state is fixed during a primary session, i.e., it cannot change states during a primary session.\u00a0 Transition between states is only allowed between primary sessions (psi parameter below).<\/span><\/p>\n

The parameters in the open robust-design multi-state model are:<\/span>
\nS<\/i>(s<\/i>) – survival rate between primary occasions for state s.<\/i><\/span>
\n<\/i>psi(r<\/i>, s<\/i>) – transition probability from state r<\/i> to state s.<\/i><\/span>
\nThe following parameters appear for each primary session.<\/span>
\npent(s<\/i>, t<\/i>) – probability of entry onto the study area of state s<\/i> at time t<\/i>.\u00a0 The probability of entering just prior to the last secondary occasion is obtained by subtraction, so that the sum of the pent values in a primary session should be constrained to <=1 using the MLogit link function<\/a>.\u00a0 An example<\/a> of how to invoke constrains and still use the MLogit link function is also provided.<\/span>
\nphi(s<\/i>, t<\/i>) – probability of remaining on the study area of state s<\/i> at time t<\/i>, given that the animal had previously entered the study area.<\/span>
\np(s<\/i>, t<\/i>) – capture probability of the animal on the study area of state s<\/i> at time t<\/i> given that the animal is on the study area at time t<\/i>.<\/span><\/p>\n

Encounter histories<\/a> are formatted as\u00a0 LLL…, i.e., only live encounters are needed, because dead encounters are not used in this data type.<\/span><\/p>\n

The identifier for this data type is 32. ORDMS: Open Robust Design Multi-state.\u00a0 In addition, there is also data type 119. ORDMSState: Open Robust Design Multi-state with State Probabilities.\u00a0 This second version includes the parameter omega that provides an estimate of the probability of being in each of the states.<\/span><\/p>\n

Three sets of derived parameters are computed.\u00a0 First, the estimated population size for each state and primary session is estimated.\u00a0 Then, 2 sets of estimates of <\/span>residence times<\/a><\/span> are computed.\u00a0<\/span><\/p>\n

Other open robust design multi-state models include <\/span>state uncertainty<\/a><\/span>.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
