This evaluation stage will produce a plot showing performance
of the model according to a certain metric described below.
The plot will be stored in a PNG file, which the user can control.
(See the output
option in evaluation_stage
).

environment. The current modeling environment. |
The plot will contain the following information:
Percent of validation samples with dep_var
= 1 on the y-axis.
Decile by model score on the x-axis. For example, if 0.1 is displayed
on the x-axis, this should be interpreted as "the best 10
by decile score" (meaning, most likely to have dep_var = 0
as
predicted by the model). If 0.2 is displayed, it means "the next best 10
of samples by decile score", that is, those falling within the 10 to 20th
percentile.
In other words, the plot describes how "good" the model is at capturing
the actual percent of samples with dep_var = 1
. The samples whose
predicted model score is within the top 10
empirical dep_var = 1
, whereas the worst 10
such percentage.
