The help file gives the example:
- Code: Select all
Xsite4,t-1 = (Wsite3 * ψsite3,t-1 + Wsite5 * ψsite5,t-1) / (Wsite3 + Wsite5 )
Are the ψ in this case unconditional psi (modeled probability only) or conditional psi (taking into account the actual detection history at that site in that year)? The papers discuss that conditional can be used, but the above help file example reads like it's just the general probability of occupancy (i.e., the unconditional psi derived parameter). If this is conditional psi, how exactly is this calculated within PRESENCE?
Thank you for your help.
