check.strata: Checks Each Stratum for Suitability for Capture-Recapture

Description

Takes in list intersection counts and source list totals as produced by make.strata. It then checks whether there are between three and five lists, whether all of the lists are non-empty, and whether all of the lists overlap with some other list.

Usage

check.strata(strata)

Value

A boolean indicating whether any serious problems have been found with the strata.

Arguments

strata

A list of list overlaps and source countsin the format of the output of make.strata. list.overlaps contains a data frame of list overlaps by stratum. source.counts contains the number of records by source and stratum.

Examples

library(chron)

N <- 1000
overlaps <- data.frame(l1 = rbinom(N, 1, .5), l2 = rbinom(N, 1, .5), l3 = rbinom(N, 1, .5))
dates <- paste(
  rep(2015, N), "-", sample(1:12, N, replace = TRUE), "-",
  sample(1:28, N, replace = TRUE)
)
dates <- chron(dates, format = c(dates = "y-m-d"))
locations <- sample(c("A", "B", "C", "D"), N, replace = TRUE)

# Aggregate only by week:
strata <- make.strata(overlaps, dates, date.def = "weekly")
check <- check.strata(strata)
