### What happened?
In the script below, I use the following method to propagate the uncertainties through a polynomial chaos expansion.
1. Create a (input, output) sample pair from the cantilever …

## Reason
Adaptive polynomial chaos selectively evaluates expansion terms based on error estimates. This approach eliminates the guess work for choosing a proper polynomial order and allows the model…

**Describe your problem**
We are using chaospy to construct the non intrusive polynomial chaos surrogate models and are looking for the mean, standard deviation, and polynomial chaos expansion coeffi…

Hi,
I am using PCE in Chaospy for my research. I can see in the documentation that you have provided an interface to some regression techniques available in Scikit-learn that contain 'coef_' attrib…

I have four normal distributions and want to add dependency to them in a simple way and than do some PCE. Lets say, I have the the correlation matrix from experimental data, my guess would be to use a…

Dear Dr.Feinberg,
I am working on polynomial chaos expansion for a very short time and I recently discovered your Python library **Chaospy**. I realized some expansions were not delivering the same…

Hi,
I'm just started to learn how to use chaospy. I want to perform polynomial chaos expansion on my interested system of ODEs, a chemical kinetics model consisted of 5-7 ODEs, which I'd apply UQ and…

In the C++ unit tests of the `FunctionalChaosAlgorithm`, we may use the exact coefficients of the Ishigami test function.
The following coefficients were computed by @regislebrun using Maple:

Hi Jonathan,
I implemented a PCE with dependent variables based on the provided tutorial.
It worked fine for my test case but I have some questions regarding its implementation.
1- What kind o…
