Computes confidence intervals for one or more parameters of fitted model. Package slca adds methods for slca fits.
Arguments
- object
an object of class
slcaandestimated.- parm
an integer string specifying parameters to be given confidence intervals.
- level
numeric value representing the desired confidence level for the intervals, with a default of 0.95.
- 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 columns are named based on the specified confidence level (level):
100 * (level / 2) %: This column shows the lower bound of the confidence interval.100 * (1 - level / 2) %: This column shows the upper bound of the confidence interval.
The level parameter specifies the confidence level, with common values being 0.05 for a 95% confidence interval and 0.01 for a 99% confidence interval.
