- What's the point of the article? That physics is
- based on statistical analysis, just like psychology?
- I never saw a t test or an anova in the Principia.

-
- But we do qualify it -- nobody in PCT is against statistics;
- we are against using statistical studies of group behavior as
- a basis for understanding individual behavior. Even when
- statistics are applied to individual behavior (it can be) we
- argue that statistics based on a causal model of behavior
- (like the general linear model) are still inappropriate --
- not, in this case, because they are statistics but because
- they are based on the wrong model of behavior.
-
- For the record -- I am NOT ANTI-STATISTICS; some of my best
- freinds are statistics. I am anti the inappropriate use of
- statistics -- as when group data is applied to individuals
- or when a linear regression model is applied to closed loop
- control.
