Computes confidence intervals for one or more parameters of a fitted model.
Arguments
- object
an object of class
slcafit.- parm
an integer or string specifying the parameters for which confidence intervals are to be computed.
- level
a numeric value representing the confidence level for the intervals. The default is
0.95(95% confidence level).- type
a character string specifying the format in which the results should be returned. Options include
"probs"for probability format and"logit"for log-odds (logit) format, with the default being"probs".- ...
additional arguments.
Value
A matrix with two columns representing the confidence intervals for the selected parameters. The column names correspond to the specified confidence level:
100 * (level / 2)%: The lower bound of the confidence interval.100 * (1 - level / 2)%: The upper bound of the confidence interval.
The level argument determines the confidence level, with common values being 0.95 for a 95% confidence interval and 0.99 for a 99% confidence interval.
