calc_synchrony: Calculate synchrony among species or locations

In James-Thorson/FishStatsUtils: Utilities (shared code and data) for FishStats spatio-temporal modeling toolbox

Calculate synchrony among species or locations

Description

calc_synchrony calculates synchrony

Usage

calc_synchrony(Report, Data, yearbounds_zz = matrix(c(1, Data$n_t), nrow = 1))

Arguments

Report	output report, e.g., from Report <- obj$report()
Data	tagged list of input data
yearbounds_zz	matrix with two columns, giving first and last years for defining one or more periods (rows) used to calculate changes in synchrony over time (only used if Options['Calculate_Synchrony']=1)

Value

Tagged list containing measures of synchrony

phi_xz

Synchrony index for each site (x) and each period (row of yearbounds_zz)

phi_z

weighted-average of phi_xz for each period, weighted by average community-abundance at each site in that period
