sksurv.functions.StepFunction#
- class sksurv.functions.StepFunction(x, y, *, a=1.0, b=0.0)[source]#
Callable step function.
\[f(z) = a * y_i + b, x_i \leq z < x_{i + 1}\]- Parameters
x (ndarray, shape = (n_points,)) – Values on the x axis in ascending order.
y (ndarray, shape = (n_points,)) – Corresponding values on the y axis.
a (float, optional, default: 1.0) – Constant to multiply by.
b (float, optional, default: 0.0) – Constant offset term.
