chaospy.Sens_t¶
- chaospy.Sens_t(poly, dist, **kws)[source]¶
Variance-based decomposition AKA Sobol’ indices
Total effect sensitivity index
- Args:
- poly (numpoly.ndpoly):
Polynomial to find first order Sobol indices on.
- dist (Distribution):
The distributions of the input used in
poly
.
- Returns:
- (numpy.ndarray) :
First order sensitivity indices for each parameters in
poly
, with shape(len(dist),) + poly.shape
.
- Examples:
>>> q0, q1 = chaospy.variable(2) >>> poly = chaospy.polynomial([1, q0, q1, 10*q0*q1-1]) >>> dist = chaospy.Iid(chaospy.Uniform(0, 1), 2) >>> chaospy.Sens_t(poly, dist) array([[0. , 1. , 0. , 0.57142857], [0. , 0. , 1. , 0.57142857]])
