Fitting Time Series Models to Fisheries Data to Ascertain Age

Figure 7

Autocorrelation function plot of the six UCMs. Dark blue indicates two standard errors from the mean. (a) Model 1 uses a stochastic level, slope, cycle, and season. (b) Model 2 uses a stochastic level and slope, no cycle, and stochastic season. (c) Model 3 uses a stochastic level, fixed slope, and stochastic cycle and season. (d) Model 4 uses a stochastic level, no slope, and stochastic cycle and season. (e) Model 5 uses a stochastic level, fixed slope, no cycle, and stochastic season. (f) Model 6 uses a stochastic level, no slope or cycle, and stochastic season.
