Description
Class for proportional interactions model (PIM).
Objects from the Class
Objects can be created by calls of the form new("pim", ...).Slots
formula:- object of codeanoint class
coef:- list of baseline (alpha), control prognostic effects (beta), and responsiveness parameter (theta)
exact:- logical indicator whether
exact fit used LRT:- likelihood ratio test statistic of responsiveness parameter
interval:- numeric vector supplied to
optimize if exact fit is used boot.pim:- matrix of bootstrap estimates of PIM coefficients
vcov:- matrix of bootstrap variance-covariance
Methods
- show
signature(object = "pim"):
Display point estimates of pim object.
- print
signature(x = "pim",...):
Display point estimates of pim object.
- summary
signature(object = "pim",...):
List of estimates and convergence information.
- coef
signature(object = "pim"):
Extractor for MLEs.
- confint
signature(object = "pim",parm,level=0.95,...):
Computes confidence interval for specified parameters and level. Intervals are based on bootstrap resamples of PIM model.
- predict
signature(object = "pim"):
Returns linear predictor for each subject.
- vcov
signature(object = "pim"):
Extractor for variance-covariance matrix which is estimated with bootstrap resampling.
