imbspace: Diagnostic tool for CEM

Description

Diagnostic tools for CEM

Usage

imbspace(obj, data, depth = 1, L1.breaks = NULL, 
plot = TRUE, fixed = NULL, minimal = 1, maximal = 6,
M=250, raw.profile=NULL)

Arguments

obj

an object of class cem.match

data

the original data.

depth

if 1, relaxes up to dropping one var, if 2 relaxes (up to dropping) two vars, etc.

L1.breaks

list of cutpoints for the calculation of the L1 measure.

plot

plot the space of solutions?

fixed

vector of variable names which will not be relaxed.

minimal

the minimal number of intervals acceptable after relaxation. Should be a nameed list of positive integers or if a number, this is applied to all variables.

maximal

the maximal number of intervals acceptable after relaxation. Should be a nameed list of positive integers or if a number, this is applied to all variables.

number of possible random coarsening for the L1 measure

raw.profile

and object of class L1profile. If passed, the L1.breaks are ignored.

Value

valan invisible object of class imbalance.space.

Details

This is a diagnostic tool to help the user in the search of different choices of coarsenings. The algorithm tries all possible combination of coarsenings into intervals between minimal and maximal one variable at time, for pairs, triplets, etc depending on the value of depth.

Calling directly plot on the output of imbspace has the same effect of calling directly imbspace.plot.
