He is well known in epidemiology thanks to his invention of what is now known as the "Nagelkerke R2", which is one of a number of generalisations of the coefficient of determination from linear regression to logistic regression, see

Pseudo-R-squared Pseudo-R-squared values are used when the outcome variable is nominal or ordinal such that the coefficient of determination 2 cannot be applied as a measure for goodness of fit and when a likelihood function is used to fit a model. In linear regr ...

Coefficient of determination In statistics, the coefficient of determination, denoted ''R''2 or ''r''2 and pronounced "R squared", is the proportion of the variation in the dependent variable that is predictable from the independent variable(s). It is a statistic used i ...
