otpod module

otpod is a module for OpenTURNS.

This package enables to build Probability of Detection (POD) curves from Non Destructive Test. The curves are built using parametric models : univariate linear regression, quantile regression, kriging and polynomial chaos. Analysis can be run in order to test the linear regression hypothesis.

PoD can be built from a set of data or directly from a given physical model that simulate the Non Destructive Test. In this case, the design of experiments is defined iteratively.

Sensitivity analysis can be also be performed. The aggregated Sobol indices are available as well as the perturbation law indices.
