Emil Julius Gumbel ( 1958 ) showed that for any well-behaved initial distribution ( i. e., F ( x ) is continuous and has an inverse ), only a few models are needed, depending on whether you are interested in the maximum or the minimum, and also if the observations are bounded above or below.

" Echoing this, Stephen Hawking states, " A theory is a good theory if it satisfies two requirements: It must accurately describe a large class of observations on the basis of a model that contains only a few arbitrary elements, and it must make definite predictions about the results of future observations.

According to him, the head was a repetition of the trunk — a kind of second trunk, with its limbs and other appendages ; this sum of his observations and comparisons — few of which he ever gave in detail — ought always to be borne in mind in comparing the share taken by Oken in homological anatomy with the progress made by other cultivators of that philosophical branch of the science.

A test that does not rely on this approximation is Fisher's exact test ; it is substantially more accurate in obtaining a significance level, especially with few observations.

Alternative models, for example, gravitational lensing, may account for a few observations of some blazars which are not consistent with the general properties.

Thus, few reports concerning these phenomena are ever published in peer reviewed scientific journals, and the lunar scientific community rarely discusses these observations.
