As mentioned in the short introduction to uncertainty quantification, there are many mature uncertainty quantification (UQ) software packages already around. They are available in most of the scientific programming lan… --- ## [RSUQ took part in the GdR MASCOT-NUM Workshop on Stochastic Simulators](https://uqworld.org/t/rsuq-took-part-in-the-gdr-mascot-num-workshop-on-stochastic-simulators/1218)

In this post, we are going to discuss stochastic simulators, a relatively new concept arising in engineering. In fact, such simulators have been widely applied in many other fields for decades, such as economics, finance… --- ## [Linear correlation, dependence, copulas, Nataf distribution and all that stuff](https://uqworld.org/t/linear-correlation-dependence-copulas-nataf-distribution-and-all-that-stuff/493)

Hello everyone I started to answer a question about linear correlation for non Gaussian random variables on the forum, and it became rather long. So I decided to move it into this section and I tried to make it comprehe… --- ## [Where to find stuff in UQWorld?](https://uqworld.org/t/where-to-find-stuff-in-uqworld/129)
