confint.cotframe {mpitbR}

Extract the confidence intervals from the the estimated changes over time measures

Description

Extract the confidence intervals from the the estimated changes over time measures

Usage

## S3 method for class 'cotframe'
confint(object, parm = "coefficient", level = 0.95, ...)

Arguments

object

a "cotframe"-class object

parm

"coefficient". Confidence intervals are only available for AF measure point estimates.

level

the confidence level required.

...

additional argument(s) for methods.

Details

The confint method for "cotframe"-class objects find the confidence intervals from the changes over time estimates data frame. This method work for only one measure c("M0","H","A","hd","hdk"). Then, user should subset the data frame with the estimates by the chosen measure (including other preferred categories, i.e., poverty cut-off, subgroup, etc.)

Value

Confidence intervals extracted from the model cotframe object.
