Functions in optmatch (0.9-0)
Search functions
caliperSize
(Internal) Determines how many other units fall within a caliper distance
effectiveSampleSize
Compute the effective sample size of a match.
caliperUpperBound
(Internal) Returns a reasonable upper bound on the arcs remaining after placing a caliper.
matched.distances
Determine distances between matched units
minControlsCap
Set thinning and thickening caps for full matching
matched
Identification of units placed into matched sets
plantdist
Dissimilarities of Some U.S. Nuclear Plants
subproblemSuccess
(Internal) Report successful subproblems.
validDistanceSpecification
(Internal) Validate that objects are valid distance specifications.
setFeasibilityConstants
(Internal) Sets up the default values for maximum feasible problems
makeInfinitySparseMatrix
(Internal) Creating sparse matching problems
maxCaliper
Find the maximum caliper width that will create a feasible problem.
fullmatch
Optimal full matching
scoreCaliper
(Internal) Helper function to create an InfinitySparseMatrix from a set of scores, a treatment indicator, and a caliper width.
setTryRecovery
(Internal) Sets up option to try recovery in
fullmatch
.
scores
Wrapper for
predict
to cleanly look for new data to predict on.
mdist
(Deprecated, in favor of
match_on
) Create matching distances
optmatch
Optmatch Class
print.optmatch
Printing
optmatch
objects.
makeOptmatch
(Internal) Create
optmatch
objects, the result of matching.
nuclearplants
Nuclear Power Station Construction Data
update.optmatch
Performs an update on an
optmatch
object.
minExactMatch
Find the minimal exact match factors that will be feasible.
pairmatch
Optimal 1:1 and 1:k matching
optmatch-defunct
Functions deprecated or removed from optmatch
dist_digest
(Internal) Remove the call before digesting a distance so things like omitting caliper and calling caliper=NULL give the same digest
subdim
Returns the dimension of each valid subproblem
exactMatch-methods
Generate an exact matching set of subproblems
optmatch_same_distance
Checks if the distance
newdist
is identical to the distance used to generate the optmatch object
obj
.
caliper
Prepare matching distances suitable for matching within calipers.
fmla2treatedblocking
(Internal) A helper function to turn formulas into treatment and blocking variables
num_eligible_matches
Returns the number of eligible matches for the distance.
optmatch_restrictions
optmatch_restrictions
getMaxProblemSize
(Internal) What is the maximum allowed problem size?
relaxinfo
Display license information about embedded code
match_on
Create treated to control distances for matching problems
stratumStructure
Return structure of matched sets
