I have left open the possibility that some is not... but it is on Cerf to give evidence something else is going on beside random testing effects.<br /><br />He hasn't.Dukehttps://www.blogger.com/profile/16535645107179796099noreply@blogger.comtag:blogger.com,1999:blog-9025948832913694345.post-56187409768100334212013-11-12T07:57:39.481-08:002013-11-12T07:57:39.481-08:00*consistently, yikes.*consistently, yikes.almhttps://www.blogger.com/profile/07420465709926105665noreply@blogger.comtag:blogger.com,1999:blog-9025948832913694345.post-10320820178916600262013-11-11T17:50:48.767-08:002013-11-11T17:50:48.767-08:00The point of the Cerf graph, as I understand it, i...The point of the Cerf graph, as I understand it, is that while lunch rate is broadly predictive of school achievement, it isn't dispositive - there are schools that break that trend, just not all that many.<br /><br />You call those data points 'noise' -- can you be more clear on what you mean?<br />If you're saying that those schools are measurement error, you'd expect to see them bubble up one year, and disappear the next. And that would be an empirical question - are there some schools that consistent 'beat the odds' year over year? <br /><br />If you're saying that those schools are noise in the sense that they aren't replicable or otherwise outliers that should be discarded, I think you need to source that. Having looked at this data before, certainly some of those schools are selective magnets or exam schools (which explains why they beat the odds - selection effects). <br /><br />But what makes them noise, in your view?almhttps://www.blogger.com/profile/07420465709926105665noreply@blogger.comtag:blogger.com,1999:blog-9025948832913694345.post-63282022953691259812013-11-11T10:43:38.747-08:002013-11-11T10:43:38.747-08:00Great post again, Jazzman.
