calc_CrI function

Calculate Credible Interval

Adds symmetric a credible interval based on quantiles.

calc_CrI(samples, summarise_by = NULL, CrI = 0.9)

Arguments

• samples: A data.table containing at least a value variable
• summarise_by: A character vector of variables to group by.
• CrI: Numeric between 0 and 1. The credible interval for which to return values. Defaults to 0.9.

Returns

A data.table containing the upper and lower bounds for the specified credible interval.

Examples

samples <- data.frame(value = 1:10, type = "car")
# add 90% credible interval
calc_CrI(samples)
# add 90% credible interval grouped by type
calc_CrI(samples, summarise_by = "type")
