Methods for estimation results

Description

Print, summarise and extract the person estimates of PP_4pl(), PP_gpcm() and PPall() (objects of class ppeo). The plots are described in pp-plots.

Usage

## S3 method for class 'ppeo'
print(x, digits = 4, ...)

## S3 method for class 'ppeo'
summary(object, nrowmax = 15, digits = 4, ...)

## S3 method for class 'ppeo'
coef(object, ...)

## S3 method for class 'ppeo'
as.data.frame(x, row.names = NULL, optional = FALSE, ...)

Arguments

x, object	An object of class ppeo.
digits	Number of significant digits to print.
...	Further arguments, passed to print().
nrowmax	When printing the estimates - how many rows should be shown? Default = 15.
row.names, optional	Ignored; the rows are the persons in the order of the response matrix.

Value

coef() returns the estimates as a vector (persons in the order of the response matrix), as.data.frame() the data.frame $estimates (estimate, SE, nsteps, status). print() and summary() return the object invisibly.
