callback (version 0.1.3)

stat_raw: Unmatched callback rates

Description

Number and proportion of callbacks for all the candidates.

Usage

stat_raw(x, method = "student", level = 0.95)

Value

A callback_stat object with 2 components: specif and props.

specif: A list containing

• convention: string "raw callback rates".

• cid: convention on 3 characters.

• method: the estimation method, "cp" for Clopper-Pearson, "wilson" for Wilson and "student" for "Student" (the default).

• level: the level of the confidence intervals (0.95 by default).

• source: the R stats function used to compute the statistics (binom.test, prop.test or t.test).

• name: the name of the statistic (Fisher, Pearson or Student).

props: a data frame containing the following variables.

• tests: number of tests

• callback: number of callbacks

• inf_p_callback: callback rate lower bound

• p_callback: callback rate

• sup_p_callback: callback rate upper bound

Arguments

x

A callback object.

method

estimation method, "cp" for Clopper-Pearson, "wilson" for Wilson and "student" for Student (the default).

level

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