Estimates of the slope parameter (and standard errors [SE]) for the fitting of the logistic model ψ(logit)φ(.), p(2 groups) along with the estimate (and lower and upper 95% confidence limits [CL]) of the average annual change defined to be ⁠, where 7 is the number of years sampled. This is the model with the highest Akaike's Information Criteria (AIC) values where a smooth change over time was represented. None of the slopes are significantly different from zero at the 5% significance level. Data are drawn from units sampled for fishers Martes pennanti from 2002 to 2009 in the southern Sierra Nevada mountains of California.
