Hi all,
I'm working with Pradel RD models and have data from 12 primary sessions and three sites. I want to examine differences in fecundity and survival between sites. Sites were trapped sequentially in a random order each session, meaning that time between sessions can vary by up to about 50% for a particular 'open' interval.
If I combine the data from all three sites and specify, say, the mean time between sites or the time between finishing the last site and starting the first one in the next session as my open time period lengths, can I then correct for the differences in time lengths simply by multiplying the monthly Phi and f values and associated CIs for each site by the appropriate differences?
ie, if the time between two sessions is 1.5 time greater for one site than the time specified when processing the data, can I just multiply the Phi and f values and CIs by 1.5?
Thanks,
Tom
