cobsurv.models.distance_functions.distance_cross_entropy

cobsurv.models.distance_functions.distance_cross_entropy(prob1, prob2, times=None)

Calculates the cross entropy between two curves at respective timepoints

Parameters:

• prob1 (1d array) – The first curve

• prob2 (1d array) – The second curve

• times (None) – times is not needed for this distance

Returns:

cross entropy – The cross entropy between the curves

Return type:

float
