Ladislaus von Bortkiewicz. Probability and statistical studies according to Keynes

Keynes was a versatile scholar and his reviewed work is widely known. Bortkiewicz notes that it was mainly concerned with the logical foundation of probability and methodology of statistical judgement. Keynes paid significant attention to the principle of indifference, unmeasurable probabilities, and to contrasting calculations with circumstances. In his paper he reproached Bortkiewicz for the estimation of precision in statistics (Bortkiewicz did not comment) and criticized both his manner of writing and his law of small numbers.
