Extract effective sample size for pooled sample

Description

Given a specified time window (defaults to current day - 14 days). calculate the effective sample size of the pooled sample over multiple pollsters.

Usage

get_pooled(
  surveys,
  last_date = Sys.Date(),
  pollsters = c("allensbach", "emnid", "forsa", "fgw", "gms", "infratest", "dimap",
    "infratestdimap", "insa"),
  period = 14,
  period_extended = NA,
  corr = 0.5,
  weights = NULL
)

Arguments

surveys	A tibble containing survey results for multiple pollsters as returned by get_surveys.
last_date	Only surveys in the time-window from last_date to last_date - period will be considered for each pollster. Defaults to current date.
pollsters	Character vector of pollsters that should be considered for pooling.
period	See last_date argument.
period_extended	Optional. If specified, all surveys in the time-window from last_date - period_extended to last_date - period will also be considered for each pollster, but only after down-weighting them by halving their true sample size.
corr	Assumed correlation between surveys (of different pollsters). Defaults to 0.5.
weights	Additional weights for individual surveys.
