Data formatting
Description
Creates the data set used in the callback package.
Usage
callback(data, cluster, candid, callback, comp = "ref")
Arguments
data |
A data frame. |
cluster |
A variable name, identifying the test (e.g., a job offer number). |
candid |
A list of factor names defining the candidates (e.g., gender, origin). |
callback |
A Boolean variable, equal to TRUE for non negative callbacks. |
comp |
An option, equal to "all" or "ref" (the default). "ref" give the comparisons with the reference candidate, and "all" the pairwise comparisons. |
Value
A list with class 'callback' containing the formatted data set (fds
),
the averaged formatted data set (afds
, for multiple tests), the list
of the paired formatted data sets (pfds
), the offer-level formatted
data set (ofds
), the names of the candidate variables (candid
)
and the name of the callback variable (callback
).
fds
contains the following variables:
cluster: the cluster variable
candid: the concatenation of the candidate variables
callback: the callback variable
afds
contains the following variables:
cluster: the cluster variable
candid: the concatenation of the candidate variables
callback: the aggregated callback dummy
pfds
data frames containing the following variables:
callback1: TRUE if candidate 1 had a callback
callback2: TRUE if candidate 2 had a callback
c00: TRUE if neither candidate was called back
c10: TRUE if candidate 1 was the only one called back
c01: TRUE if candidate 2 was the only one called back
c11: TRUE if both candidates were called back
callback: TRUE if either candidate was called back
calldif: callback difference
ofds
contains variables corresponding to the candidates' codes and the
following variables:
cluster: the cluster variable
ncall: the number of callback for the current offer
