matchMultioutcome: Performs an outcome analysis after multilevel matching.

In matchMulti: Optimal Multilevel Matching using a Network Algorithm

Performs an outcome analysis after multilevel matching.

Description

This function returns a point estimate, 95% confidence interval, and p-values for the matched multilevel data. All results are based on randomization inference.

Usage

matchMultioutcome(
  obj,
  out.name = NULL,
  schl_id_name = NULL,
  treat.name = NULL,
  end.1 = -1000,
  end.2 = 1000
)

Arguments

obj	A multilevel match object.
out.name	Outcome variable name
schl_id_name	Level 2 ID variabel name. This variable identifies the clusters in the data that you want to match.
treat.name	Treatment variable name, must be zero or one.
end.1	Lower bound for point estimate search, default is -1000.
end.2	Upper bound for point estimate search, default is 1000.

Details

It may be necessary to adjust the lower and upper bounds if one expects the treatment effect confidence interval to be outside the range of -1000 or 1000.

Value

pval.c	One-sided approximate p-value for test of the sharp null.
pval.p	One-sided approximate p-value for test of the sharp null assuming treatment effects vary with cluster size
ci1	Lower bound for 95% confidence interval.
ci2	Upper bound for 95% confidence interval.
p.est	Point estimate for the group level treatment effect.

Examples

	## Not run: 
# Load Catholic school data
data(catholic_schools)

student.cov <- c('minority','female','ses','mathach')

# Check balance student balance before matching
balanceTable(catholic_schools[c(student.cov,'sector')],  treatment = 'sector')

#Match schools but not students within schools
match.simple <- matchMulti(catholic_schools, treatment = 'sector',
school.id = 'school', match.students = FALSE)

#Check balance after matching - this checks both student and school balance
balanceMulti(match.simple, student.cov = student.cov)

#Estimate treatment effect
output <- matchMultioutcome(match.simple, out.name = "mathach",
schl_id_name = "school",  treat.name = "sector")
