Get summary statistics from draws (of counts)

summ_sims(sims, area_var = "cd", est_var = "p_mrp", dtplyr = TRUE)

Arguments

sims

output of poststrat_draws

area_var

A character string for the variable name(s) for area to group and aggregate by. That is, the area of interest in MRP. Defaults to "cd"

est_var

column name with estimates. Following the output of poststrat_draws, defaults to p_mrp.

dtplyr

Whether to use a data.table/dtplyr backend for processing for slightly faster dataframe wrangling. Currently does not apply to anything within the function.

Examples

if (FALSE) {
drw_GA <- poststrat_draws(fit_GA, poststrat_tgt = acs_GA)
summ_sims(drw_GA, area_bar = "cd") # also saved as data(`summ_GA`)

# To create summaries by both CD and education
drw_GA_educ <- poststrat_draws(fit_GA, poststrat_tgt = acs_GA, area_var = c("cd", "educ"))
summ_sims(drw_GA_educ, area_var = c("cd", "educ"))

}
