Experiment Advisor Monitoring

[David McFarlane]

Valerio,

You can puzzle this out for yourself.  Try the following.  Open a 
blank (Professional) experiment.  Run it.  Now look at the resulting 
ExperimentAdvisorReport.xml.  See the Experiment Advisor Modules 
table?  Does it include all the same items as before, even though the 
experiment is completely blank?

Now disable some of the Experiment Advisor Modules.  E.g., back in 
E-Studio, open the Experiment Object Properties, go to the Experiment 
Advisor tab, and disable "Use of ClearAfter" and "Use of 
Stretch".  Run this, open the resulting ExperimentAdvisorReport.xml, 
and look at the Experiment Advisor Modules table.  Do you see that 
"An object has its ClearAfter property set to Yes..." and "A visual 
object has its Stretch property set to Yes..." have both disappeared?

 From this evidence would you conclude that the Experiment Advisor 
Modules table tells you only what modules were enabled, and not what 
problems it found?  Would you find this useful, because without this 
information you could not tell whether the lack of a warning only 
meant that that test was not run?

As usual, do not take my word for any of this, test it out for 
yourself.  I presented my answer this way because I need to stress 
that I do not have any inside knowledge about E-Prime, I simply 
figure it out exactly as I outlined above.

Best regards,
