compute_z_aggregates: Compute z_ Aggregates from Monthly Microdata

In PNADCperiods: Identify Reference Periods in Brazil's PNADC Survey Data

Compute z_ Aggregates from Monthly Microdata

Description

Computes monthly z_ aggregates from PNADC microdata using calibrated monthly weights, with options for different population scaling approaches.

Usage

compute_z_aggregates(calibrated_data, verbose = TRUE)

Arguments

calibrated_data	PNADC microdata output from pnadc_apply_periods() with calibrate = TRUE. Must include weight_monthly, ref_month_yyyymm, and ref_month_in_quarter.
verbose	Print progress messages.

Details

This function creates z_ indicator variables and aggregates them using the calibrated weight_monthly from pnadc_apply_periods().

The pnadc_apply_periods() function implements the calibration methodology as follows: All months are scaled uniformly to SIDRA monthly population totals.

This function simply aggregates the indicators using the already-calibrated weights.

Value

data.table with columns:

anomesexato

Integer YYYYMM month

z_*

Numeric weighted aggregates for each series (one column per series)
