Influence of simulated direction of trend in annual counts and magnitude and pattern of change in stopover duration (indexed by daily survival probability phii) on bias of estimated trends.

Reference categories for the independent variables in the linear regression model were no trend (Trend = 0%year-1), random variation in stopover duration, and a range in phii values between 0.40–0.50.Influence of simulated direction of trend in annual counts and magnitude and pattern of change in stopover duration (indexed by daily survival probability phii) on bias of estimated trends.
