.get_synth_draws {bsynth}

Get Synthetic Draws in Tidy Format for Single Treated Unit

Description

This internal helper function extracts synthetic draws from a Stan fit object, combines them with observed outcome data, and returns a tidy data frame suitable for further analysis or plotting. This function is specifically designed for scenarios with a single treated unit.

Usage

.get_synth_draws(fit, pre_data, post_data, time, outcome)

Arguments

fit

A Stan fit object containing the model results.

pre_data

A data frame with outcome data before the intervention.

post_data

A data frame with outcome data after the intervention.

time

The name of the time period variable (as a string).

outcome

The name of the outcome variable (as a string).

Value

A data frame containing:

• draw: The index of the synthetic draw.

• time: The time period.

• y_synth: The synthetic outcome for the given draw and time period.

• outcome: The observed outcome for the given time period.
