"To remove a very critical part of the scientific understanding is nothing short of political censorship and has no place in science," he said. "Censorship of this kind is something you'd see in Russia or some totalitarian regime. It has no place in America."
Better safe than sorry, perhaps, but have the courage of your convictions; or give both; or ask me if it matters!
That may have been what was written in the key, but those solutions are not perfect -- what is? -- but meant as a good guide. A better phrase is that "the model is rejected, based on a certain criterion" (in this case 95% confidence). If we'd used 90% confidence, we would not have rejected the model. So just what, exactly, was "inappropriate"? Perhaps it was choosing 95% confidence!
I told you in class that I searched for the source for the data, and also searched for models of sea anemone "standard size", which is referenced in the original article containing the data -- to no avail. So it was left to our imaginations just what "size" referred to.
If "size" were area A, and if the response duration were based on distance (i.e. length), then the response duration would be proportional to distance, which is proportional to $\sqrt{A}$.
And so a model is born....
But my inclination is that, if one of them is significant, I'll keep both (not throw them both out if one of them is not significant).
Those are sort of anti-symmetric policies, do you agree?
There are two models discussed, and today we'll hit the first, because it gives us an opportunity: we have the opportunity to create a small simulation experiment, to address one of the issues (criticisms, really) Olinick raises.
Under what conditions will the age-grade system be stable?
So Hoffmann sought to address this issue of stability with a definition, an axiom, and two different models.
Ask someone who's had a child at the age of 40....
As the author [Prins] remarks, some social recognition of growth and aging is universal. In East Africa, however, this recognition of the aging process has developed into a complex social institution that should be called a social age-class system. To a degree, actual age is ignored in favor of other criteria for entering a given age class. Thus, all the sons of a Galla man, and all the sons of his brothers, enter the same age class which is forty years behind that of their fathers. The author has coined the terms "infra-puerilization" for cases where the actual years are less than their social years and "ultra-senectation" for those individuals who are too old for their age classes. The prohibition against fatherhood for the warrior class is seen as a device that reduces ultra-senectation where, as with the Galla, the social age separating father and son is so great.
....Each Galla male is supposed to go through five age classes, each of eight years' duration. The first two classes are for children, the third and half of the fourth are for warriors, while the second half of the fourth and the fifth are for elders. The forty-year interval rule discussed in the previous paragraph keeps all members of a given patrilineal line of the same generation in the same age class. [my emphasis]
