compile_pseudo_pop: Compile Pseudo Population

In wxwx1993/GPSmatching: Matching on Generalized Propensity Scores with Continuous Exposures

Compile Pseudo Population

Description

Compiles pseudo population based on the original population and estimated GPS value.

Usage

compile_pseudo_pop(
  data_obj,
  ci_appr,
  gps_model,
  bin_seq,
  nthread,
  optimized_compile,
  ...
)

Arguments

data_obj	A S3 object including the following: Original data set + GPS values (Y, w, GPS, counter, row_index, c) e_gps_pred e_gps_std_pred w_resid gps_mx (min and max of gps) w_mx (min and max of w).
ci_appr	Causal inference approach.
gps_model	Model type which is used for estimating GPS value, including parametric and non-parametric.
bin_seq	Sequence of w (treatment) to generate pseudo population. If NULL is passed the default value will be used, which is seq(min(w)+delta_n/2,max(w), by=delta_n).
nthread	An integer value that represents the number of threads to be used by internal packages.
optimized_compile	If TRUE, uses counts to keep track of number of replicated pseudo population.
...	Additional parameters.

Value

compile_pseudo_pop returns the pseudo population data that is compiled based on the selected causal inference approach.

Note

The input data set should be output of estimate_gps function with internal_use flag activated.
