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.
