makeRBPObj(pred, y, positive = NULL)
Object members:
n
[numeric(1)
]Number of observations.
pred
[numeric(n)
]Predicted probabilities.
y
[numeric(n)
]Target variable having the values 0 and 1.
positive
[character(1)
]Positive class label of traget variable. Only present when y
is a factor.
e0
[numeric(1)
]Average of the predicted probabilities conditional on y=0
.
e1
[numeric(1)
]Average of the predicted probabilities conditional on y=1
.
pev
[numeric(1)
]Proportion of explained variation measure. Computed as e1-e0
.
tpr
[numeric(1)
]True positive rate.
fpr
[numeric(1)
]False positive rate.
prev
[numeric(1)
]Prevalence.
one.min.prev
[numeric(1)
]One minus the value of the prevalence.
axis.x
[numeric(n)
]Values for the X-Axis of the RBP curve.
axis.y
[numeric(n)
]Values for the Y-Axis of the RBP curve.
[numeric
]
Predicted probabilities for each observation.
[numeric
| factor
]
Class labels of the target variable.
Either a numeric vector with values 0
or 1
, or a factor with two levels.
[character(1)
]
Set positive class label for target variable which is transformed as 1
to compute.
Only needed when y
is a "factor".
