Why does Taylor's law in human mortality data have slope less than 2, contrary to the Gompertz model?

by Joel E. Cohen

Response by Joel E. Cohen, Christina Bohk-Ewald, Roland Rau to comments by Michel Guillot and Carl Schmertmann

The central theoretical result of Cohen, Bohk-Ewald and Rau (2018) states that the Gompertz mortality model with modal age at death increasing linearly in time obeys a [...]

More general set of conditions producing a Taylor’s Law with an exact slope of 2

by Michel Guillot

In the attached letter, I propose a set of conditions producing Taylor's Law (TL) with an exact slope of 2 that is more general than in the Cohen, Bohk-Ewald, and Rau study. This result emphasizes the importance of time trends rather than age patterns of mortality for understanding TL slopes.
