summary.mlr: Applying diagnostic and calibration functions to mlr objects

In MatchLinReg: Combining Matching and Linear Regression for Causal Inference

Applying diagnostic and calibration functions to mlr objects

Description

Applying a series of diagnostic and calibration functions to a series of matched data sets to determine impact of matching on TE bias, variance and total error, and to select the best matching parameters.

Usage

## S3 method for class 'mlr'
summary(object, power = FALSE
  , power.control = list(rnd = TRUE, d = 0.5, sig.level = 0.05
    , niter = 1000, rnd = TRUE)
  , max.method = c("single-covariate", "covariate-subspace"
    , "absolute")
  , verbose = FALSE, ...
  , orsq.min = 1e-03, orsq.max = 1e0, n.orsq = 100)

Arguments

object	An object of class mlr, typically the result of a call to mlr.
power	Boolean flag indicating whether Monte-Carlo based power analysis must be performed or not.
power.control	A list containing parameters to be passed to mlr.power for power calculation.
max.method	Which constrained bias estimation method must be used in bias-variance trade-off and other analyses?
verbose	Whether progress message must be printed.
...	Parameters to be passed to/from other functions.
orsq.min	Minimum value of omitted R-squared used for combining normalized bias and variance.
orsq.max	Maximum value of omitted R-squared used for combining normalized bias and variance.
n.orsq	Number of values for omitted R-squared to generate in the specified range.

Value

An object of class summary.mlr, with the following elements:

mlr.obj	Same as input.
bias	Matrix of aggregate bias values, one row per calibration index, and three columns: 1) single-covariate maximum, 2) covariate-subspace maximum, and 3) absolute maximum, in that order.
bias.terms	Matrix of biases, one row per calibration index, and one column per candidate omitted term.
variance	Vector of normalized variances, one per each value of calibration index.
power	Matrix of power calculations, one row per calibration index. Each row is identical to output of mlr.power for that calibration index value.
smd	Matrix of standardized mean differences, one row per calibration index, and one column for each included or omitted covariates.
combine.obj	Output of mlr.combine.bias.variance applied to bias and variances at each calibration index value.
