stat_glob {callback}

Unmatched callback rates

Description

Number and proportion of callbacks for all the candidates.

Usage

stat_glob(x, level = 0.95)

Arguments

x

A callback object.

level

A number, containing the level of the confidence intervals (0.95 by default).

Value

A stat_glob object with 5 components : level, props, cp, wilson and student.

level: the level of the confidence intervals

props: a data frame containing the following variables.

• tests: number of tests.

• callback: number of callbacks.

• p_callback: callback rate.

cp, wilson and student are data frames containing the following variables:

• inf_p_callback: callback rate lower bound.

• sup_p_callback: callback rate upper bound.
