Survivorship

Survivorship bias is the logical error of concentrating on the people or things that "survived" some process and inadvertently overlooking those that did not because of their lack of visibility.

When it is remembered that these cases outnumber all others—that there are more species of parasites than there are species of all other animals put together—it will be seen that the expression "survivorship of the better" is wholly inappropriate, and the argument Mr. Martineau bases upon it quite untenable.

We therefore seek a method for response-function normalization method which involves manipulating empirical curves that result from unconstrainted empirical fits of the corrected survivorship data.
