Judging the Autism Charts Challenge
When writing this entry on the difficulty of displaying data when diagnosing Autism at age 2, I did not expect such a large number of people putting their minds into making the graphs better. Andrew Gelman and Masanao Yajima made a challenge out of it. It got picked up by the folks at JunkCharts, EagerEyes.org, and at Perceptual edge and much brain computing cycle went into this Challenge. Previously, I had already stated that I thought Autism was a Grand Challenge and this is in no small part because the diagnosis phase is not early enough, not accurate enough and sometimes not useful enough.
- Not early enough is the reason why this study [1] by Catherine Lord was performed. Instead of taking a "normal" test at age 3, age 2 is preferred with regards to intervention.
- Not accurate enough and not useful: there is currently very little difference whatsoever in treatment between kids that have been diagnosed Autistic or with Pervasive Developmental Disorder- Not Other Specified (PDD-NOS).




Please go to Andrew Gelman and Masanao Yajima's blog and answer the survey at the very end. Please note there are TWO questions.
- Which plot did you like best?
- Which plots did you find useful?

Well thank you for the challenge! There is more I wanted to do with this data, but I just haven't found the time to do it yet. I'm thinking that the false positives vs. false negatives would be interesting to investigate further, because I don't feel we have really gotten to the bottom of that yet. But we have shown that there are a lot of much better alternatives to the Venn diagram ;)
You do plan to submit these back to the original paper author, right?
Robert:
Absolutely agree on the Venn diagram usefulness.
Charles:
I have mentioned the challenge to Catherine Lord but I have not heard back from her. But I intend on pressing this issue as she has gathered additional data since that paper was published.
