compute_starting_points_from_microdata: Compute Starting Points from Raw PNADC Microdata

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

Compute Starting Points from Raw PNADC Microdata

Description

Complete workflow to compute y0 starting points from raw PNADC microdata. This is a convenience wrapper that combines period identification, weight calibration, z_ aggregation, and starting point computation.

Usage

compute_starting_points_from_microdata(
  data,
  calibration_start = NULL,
  calibration_end = NULL,
  verbose = TRUE
)

Arguments

data	Stacked PNADC microdata (multiple quarters). Must contain variables for period identification (see pnadc_identify_periods).
calibration_start	Integer. Start of calibration period (YYYYMM). Default NULL uses .PNADC_DATES$DEFAULT_CALIB_START (201301).
calibration_end	Integer. End of calibration period (YYYYMM). Default NULL uses .PNADC_DATES$DEFAULT_CALIB_END (201912).
verbose	Print progress messages.

Details

This function performs the complete workflow:

1. Build crosswalk via pnadc_identify_periods()

2. Calibrate weights via pnadc_apply_periods()

3. Compute z_ aggregates via compute_z_aggregates()

4. Fetch SIDRA rolling quarters

5. Compute starting points via compute_series_starting_points()

Value

data.table with columns:

series_name

Character. Series name

mesnotrim

Integer. Month position (1, 2, or 3)

y0

Numeric. Starting point value

Weight Calibration

All months are scaled uniformly to SIDRA monthly population totals.

Examples

## Not run: 
stacked <- fst::read_fst("pnadc_stacked.fst", as.data.table = TRUE)

y0 <- compute_starting_points_from_microdata(stacked)

bundled <- pnadc_series_starting_points
comparison <- merge(y0, bundled, by = c("series_name", "mesnotrim"))
