polycuts {repolr} | R Documentation |
After fitting a model using repolr
, function polycuts
gives estimates and standard errors for the K-1 cut-point parameters, based on the polynomial model from the fit of repolr
. Polynomial cut-point parameter estimates from the orginal model are also shown.
polycuts(object, digits = 3, robust.var = TRUE)

is a model fitted using |
digits |
the number of decimal places to display in reported summaries. |
robust.var |
a logical variable: if |
coef |
polynomial parameter estimates from |
poly |
a vector of K-1 cut-point parameters. |
order |
the order of the polynomial. |
