summary.qrmix: Summarizing qrmix Fits

In qrmix: Quantile Regression Mixture Models

Description

summary method for class "qrmix"

Usage

## S3 method for class 'qrmix'
summary(object, fitMethod=NULL, data=NULL, ...)

Arguments

object	an object of class "qrmix".
fitMethod	an optional refitting method if the user wants a method different than the one used to obtain "object" Use "lm" for OLS, "rlm" for robust regression, and "rq" to use fit from quantile regression.
data	data used to fit object if it is not contained in object.
...	other argumets passed to other methods.

Value

residuals	the residuals, response minus fitted values.
clusters	cluster assignment for each observation.
call	the matched call.
fitMethod	the fitting method used to obtain residuals and clusters.
quantiles	the set of k quantiles that minimize the mean loss.
clusters#	generic summary from function fitMethod for data in cluster #.

Examples

data(blood.pressure)

#qrmix model using default function values:
mod1 = qrmix(bmi ~ ., data = blood.pressure, k = 3)

#summary using fitMethod = "rlm" instead of the one used when fitting the model mod1
summary1 = summary(mod1, fitMethod = "rlm")

#Are the quantiles selected in this case the same as in the original model?
summary1$quantiles
mod1$quantiles
