comparePercChange

Description

this function calculates 3 alternative versions of the Perc Change metric: 1 deterministic (MLE) and 2 Bayesian (JAGS via rjags, STAN via RStanArm)

Usage

comparePercChange(
  du.label,
  du.df,
  yrs.window,
  calc.yr,
  samples.out = TRUE,
  plot.pattern = TRUE,
  plot.posteriors = TRUE,
  plot.boxes = TRUE
)

Arguments

du.label	short label for the the Designatable Unit (DU)
du.df	data frame with the DU time series for : 2 columns, first one is "Year", second the abundance.
yrs.window	number of years to use for the percent change calculation (e.g. 3 gen +1)
calc.yr	year for which the perc change is calculated
samples.out	if TRUE, include the posterior samples in the output
plot.pattern	if TRUE, create a plot of the time series with alternative slope estimates
plot.boxes	if TRUE, create a plot of the posterior distributions (box plots)
plot.distributions	if TRUE, create a plot of the posterior distributions (kernel density plot)
