<div class=AutoScaleImage>[[ File:Dakota_logo.jpg | Dakota | right | link=https://dakota.sandia.gov ]]<div> 

[https://dakota.sandia.gov Dakota], developed at Sandia National Laboratories,
is a software toolkit
that provides an interface between computational models and a library of iterative systems analysis methods.
Dakota helps answer questions such as:
*  What are the most influential parameters in my model? → '''sensitivity analysis'''
* How robust and reliable is my model? → '''uncertainty quantification'''
* What is the best performing design? → '''optimization'''
* What model parameter values best match experimental data? → '''calibration'''

Dakota has an extensive library of analysis techniques, including:
* parameter studies
* design of experiments 
* design of computer experiments (DACE)
* sampling (MC or LHS)
* local and global reliability
* adaptive sampling
* stochastic expansion
* epistemic methods
*  gradient-based local and global optimization
* derivative-free local and global optimization
* nonlinear least squares
* surrogate models
