Keynes among the statisticians
This paper considers J. M. Keynes as a statistician and philosopher of statistics and the reaction of English statisticians to his critique of their work. It follows the development of Keynes's thinking through the two versions of his fellowship dissertation The Principles of Probability (1907/8) to his book A Treatise on Probability (1921). It places Keynes's ideas in the context of contemporary English and Continental statistical thought. Of the statisticians considered special attention is paid to the reactions of four: Edgeworth, Bowley, Jeffreys and R. A. Fisher<br/

Collected Notes on Aldrich-Mckelevey Scaling
Aldrich-McKelvey scaling is a method for correcting differential item
functioning in ordered rating scales of perceived ideological positions in
surveys. In this collection of notes, I present four findings. First, I show
that similarly to ordinary least squares, Aldrich-McKelvey scaling can be
improved with the use of QR decomposition during the estimation stage. While in
theory this might improve accuracy, in practice the main advantage is to retain
respondents otherwise lost in the estimation stage. Second, I show that this
method leads to a proof of an identification constraint of Aldrich-McKelvey
scaling: a minimum of three external stimuli. Third, I show that the common
motivation for Aldrich-McKelvey scaling that it is robust to heteroskedasticity
as compared to taking the means does not hold up. A review of the literature of
prediction aggregation shows taking the mean is equally as robust. However,
Aldrich-McKelvey scaling remains robust to rationalization bias and is
transparent in its assumptions. Finally, I show that the setup of Bayesian
Aldrich-McKelvey Scaling and Aldrich-McKelvey scaling differ from each other in
their parameterisation. This is not commonly acknowledged in the literature,
and new users of these methods should be aware
