Functions in optmatch (0.9-1)

effectiveSampleSize

Compute the effective sample size of a match.

exactMatch-methods

Generate an exact matching set of subproblems

matched

Identification of units placed into matched sets

match_on

Create treated to control distances for matching problems

subproblemSuccess

(Internal) Report successful subproblems.

fmla2treatedblocking

(Internal) A helper function to turn formulas into treatment and blocking variables

optmatch-defunct

Functions deprecated or removed from optmatch

optmatch_restrictions

matched.distances

Determine distances between matched units

caliperSize

(Internal) Determines how many other units fall within a caliper distance

scoreCaliper

(Internal) Helper function to create an InfinitySparseMatrix from a set of scores, a treatment indicator, and a caliper width.

caliperUpperBound

(Internal) Returns a reasonable upper bound on the arcs remaining after placing a caliper.

minExactMatch

Find the minimal exact match factors that will be feasible.

nuclearplants

Nuclear Power Station Construction Data

pairmatch

Optimal 1:1 and 1:k matching

print.optmatch

Printing optmatch objects.

setFeasibilityConstants

(Internal) Sets up the default values for maximum feasible problems

update.optmatch

Performs an update on an optmatch object.

num_eligible_matches

Returns the number of eligible matches for the distance.

subdim

Returns the dimension of each valid subproblem

validDistanceSpecification

(Internal) Validate that objects are valid distance specifications.

makeInfinitySparseMatrix

(Internal) Creating sparse matching problems

optmatch

Optmatch Class

caliper

Prepare matching distances suitable for matching within calipers.

fullmatch

Optimal full matching

dist_digest

(Internal) Remove the call before digesting a distance so things like omitting caliper and calling caliper=NULL give the same digest

makeOptmatch

(Internal) Create optmatch objects, the result of matching.

mdist

(Deprecated, in favor of match_on) Create matching distances

getMaxProblemSize

(Internal) What is the maximum allowed problem size?

relaxinfo

Display license information about embedded code

minControlsCap

Set thinning and thickening caps for full matching

setTryRecovery

(Internal) Sets up option to try recovery in fullmatch.

optmatch_same_distance

Checks if the distance newdist is identical to the distance used to generate the optmatch object obj.

plantdist

scores

Wrapper for predict to cleanly look for new data to predict on.

stratumStructure

Return structure of matched sets

maxCaliper

Find the maximum caliper width that will create a feasible problem.
