Assessing the power to detect systematic change in Adélie penguin foraging trip duration
for years i = 1,2,…,a prior to an impact (i.e. Mi = M0), then in the year follow- ing an impact mean trip ... duration may increase by a proportion p and remain at that changed level thereafter (i.e. Mi = M0 ... (1 + p) for i = a+1,a+2,…,a+b thereafter). This can be equivalently expressed on a logarithmic scale as: logMi = logM0 for i = 1,2 ... after an impact (i.e. Mi+1 = Mi + pMi, or 1 1i i M p M + = + , where Mi is the expected trip ...
