summary.microsynth {microsynth}

Summarizing microsynth Fits and Results

Description

Summary method for class 'microsynth'.

Usage

## S3 method for class 'microsynth'
summary(object, ...)

Arguments

object

A microsynth object produced by microsynth()

...

further arguments passed to or from other methods.

Value

The functions print.microsynth and summary.microsynth displays information about the microsynth fit and estimation results, if available.

The output includes two parts: 1) a matching summary that compares characteristics of the treatment to the synthetic control and the population; and 2) estimated results, in a similar format as they appear when saved to .csv or .xlsx., once for each specified post-intervention evaluation time.

Examples

# Use seattledmi, block-level panel data, to evaluate a crime intervention.

# Declare time-variant (outcome) and time-invariant variables for matching
cov.var <- c('TotalPop', 'BLACK', 'HISPANIC', 'Males_1521',
       'HOUSEHOLDS', 'FAMILYHOUS', 'FEMALE_HOU', 'RENTER_HOU', 'VACANT_HOU')

match.out <- c('i_felony', 'i_misdemea', 'i_drugs', 'any_crime')
set.seed(99199) # for reproducibility

# Perform matching and estimation, without permutations or jackknife
# runtime: < 1 min

                  idvar='ID', timevar='time', intvar='Intervention',
