Hi Edward. What do you think about this bug report? I added some figures, showing that the parameter values does not represent the expectation value of the Monte-Carlo simulation distribution. Best Troels 2015-06-15 11:32 GMT+02:00 Troels E. Linnet < NO-REPLY.INVALID-ADDRESS@xxxxxxx>:
URL: <http://gna.org/bugs/?23644> Summary: monte_carlo.error_analysis() does not update the mean value/expectation value from simulations Project: relax Submitted by: tlinnet Submitted on: Mon 15 Jun 2015 09:32:07 UTC Category: None Specific analysis category: None Priority: 5 - Normal Severity: 3 - Normal Status: None Assigned to: None Originator Name: Originator Email: Open/Closed: Open Release: Repository: trunk Discussion Lock: Any Operating System: All systems _______________________________________________________ Details: When performing a monte_carlo.error_analysis(), the error for each parameter is estimated by the Standard deviation for all the simulated values. But the mean of these simulated values is not used to update parameter value. Therefore, this leads to a rather weird situation, where the described parameter error is from the width of a simulated distribution, and and the expectation value is not updated. Some few histograms is added to show this. _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Mon 15 Jun 2015 09:32:07 UTC Name: figure1.png Size: 32kB By: tlinnet <http://gna.org/bugs/download.php?file_id=24577> ------------------------------------------------------- Date: Mon 15 Jun 2015 09:32:07 UTC Name: figure3.png Size: 35kB By: tlinnet <http://gna.org/bugs/download.php?file_id=24578> ------------------------------------------------------- Date: Mon 15 Jun 2015 09:32:07 UTC Name: figure2.png Size: 36kB By: tlinnet <http://gna.org/bugs/download.php?file_id=24579> _______________________________________________________ Reply to this item at: <http://gna.org/bugs/?23644> _______________________________________________ Message sent via/by Gna! http://gna.org/
