Hello  
Can Uqpylab define the distribution for all input variables? if not, how we define this distribution from data?  
Thank you

Hi Hamdaoui\_Khaled,  
Is it possible to take a look at the input definition in UQLab? [https://www.uqlab.com/input-user-manual](https://www.uqlab.com/input-user-manual)  
Would this help answer your question?  
Regards
