General matrix and other utilities for statistics
Bases: object
A basic step function: values at the ends are handled in the simplest way possible: everything to the left of x[0] is set to ival; everything to the right of x[-1] is set to y[-1].
Examples
>>> x = np.arange(20)
>>> y = np.arange(20)
>>> f = StepFunction(x, y)
>>>
>>> print f(3.2)
3.0
>>> print f([[3.2,4.5],[24,-3.1]])
[[ 3. 4.]
[ 19. 0.]]
Return the ECDF of an array as a step function.
Median Absolute Deviation:
median(abs(a - median(a))) / c
Given a monotone function x (no checking is done to verify monotonicity) and a set of x values, return an linearly interpolated approximation to its inverse from its values on x.
