plot.UPSnnltd {USPS}

Display plots of the NN/LTD Distribution in Unsupervised Propensiy Scoring
Package: 
USPS
Version: 
1.2-2

Description

Make a Snow Ball ("snob"), Probability Density ("dens") and/or Cumulative Distribution Function ("cdf") plot of the Local Treatment Difference (LTD) Distribution across all Informative Clusters within a requested total number clusters in patient baseline X-covariate space.

Usage

 
## S3 method for class 'UPSnnltd':
plot((x, pballs = TRUE, nnplot = "snob", nnalpha = 1.4, ...))

Arguments

x
Object of class UPSnnltd.
pballs
Logical; Display cluster-size weighted (red) and inverse-variance weighted (green) "Power Balls" to represent across cluster LTD averages within the "Snowball" plot.
nnplot
String; Display "all" plots together, "seq" = one after the other, "snob" = only Snow Balls, "dens" = only fitted gss probability density, or "cdf" = only the gss cumulative distribution.
nnalpha
Numeric; alpha argument to ssden() function.
...
Optional argument(s) to pass on to plot().

Details

Plots of UPSnnltd objects describe the LTD Distribution across all informative clusters. The generalized smoothing spline (gss) displays corresponding to the nnplot = "dens" and "cdf" options may fail to exist when the number of informative clusters is less than 60.

Values

NULL
