lookup_estimates

Description

Look up and read in existing estimates from pre-calculated files.

Usage

lookup_estimates(stratum_data_prepped, estimates_dir)

Arguments

stratum_data_prepped	A data frame including all records in a stratum of interest. The data frame should only include the source columns prefixed with in_ and all columns should only contain 1's and 0's.
estimates_dir	Directory containing pre-calculated estimates, if you would like to use pre-calculated results. Note, setting this option forces the model specification parameters to be identical to those used to calculate the pre-calculated estimates. Do not specify a file path If you would like to use a custom model specification.

Value

A data frame with one column, N, indicating the results. If the stratum was not found in the pre-calculated files, N will be NA and the data frame will have one row. If the stratum was found in the pre-calculated files, N will contain draws from the posterior distribution of the model and the data frame will contain 1,000 rows.

Examples

in_A <- sample(c(0, 1), size = 100, replace = TRUE, prob = c(0.45, 0.65))
in_B <- sample(c(0, 1), size = 100, replace = TRUE, prob = c(0.5, 0.5))
in_C <- sample(c(0, 1), size = 100, replace = TRUE, prob = c(0.75, 0.25))
in_D <- sample(c(0, 1), size = 100, replace = TRUE, prob = c(1, 0))

my_stratum <- tibble::tibble(in_A, in_B, in_C, in_D) %>%
    dplyr::mutate(rs = rowSums(.)) %>%
    dplyr::filter(rs >= 1) %>%
    dplyr::select(-rs)

lookup_estimates(stratum_data_prepped = my_stratum, estimates_dir = "path_to_estimates")
