\title{Starting Points for SIDRA Series Mensalization}
\format{
A data.table with 159 rows and 3 columns:
\describe{
\item{series_name}{Character. Name of the SIDRA series (53 series)}
\item{mesnotrim}{Integer. Month position in quarter (1, 2, or 3)}
\item{y0}{Numeric. Starting point value for this series and position}
}
}
\source{
Computed using \code{data-raw/regenerate_starting_points_from_microdata.R}
}
\usage{
data(pnadc_series_starting_points)
}
\description{
Pre-computed starting point values (y0) for mensalizing IBGE's rolling
quarterly series into exact monthly estimates.
}
\details{
These starting points were computed from PNADC microdata using the full
R package pipeline, ensuring consistency with
\code{\link{compute_starting_points_from_microdata}}:
\enumerate{
\item Weight calibration via \code{\link{pnadc_apply_periods}}: all months
scaled to SIDRA monthly population totals
\item z_ aggregates computed via \code{\link{compute_z_aggregates}} using
calibrated \code{weight_monthly}
\item Starting points computed via \code{\link{compute_series_starting_points}}
with CNPJ-aware calibration periods
}

The calibration period (2013-2019) was chosen because:
\itemize{
\item It includes stable pre-pandemic data
\item IBGE methodology was consistent during this period
\item Sufficient observations for reliable estimates
}

CNPJ series (empregadorcomcnpj, empregadorsemcnpj, contapropriacomcnpj,
contapropriasemcnpj) use calibration period 2016-2019 with cumulative sum
starting from October 2015 due to V4019 variable availability.
}
\section{Methodology Consistency}{

The bundled starting points are generated using the same pipeline as
\code{\link{compute_starting_points_from_microdata}}, ensuring that users
who compute custom starting points will get consistent results.
}

\section{When to Use Custom Starting Points}{

The bundled starting points are suitable for most users. Consider computing
custom starting points with \code{\link{compute_starting_points_from_microdata}} if:
\itemize{
\item IBGE makes major methodological changes to the PNADC
\item You need series not included in the bundled data
\item You want to use a different calibration period
\item You are working with updated or different microdata
}
}
