During the First World War he was a statistician to the director of army contracts and the Ministry of Food. Yule was very influential in the fledgling discipline of statistics, and an active member of several scientific societies, but he also had an interest in medieval devotional literature, and studied Latin in later life, alongside motoring and flying.

His interest in literature led him to attempt a statistical study of the vocabulary of the devotional work Imitatio Christi to ascertain its authorship. Yule left all his books to St John's to dispose of, and there are currently over items which bear his provenance. Selected works [ edit ]. References [ edit ].

Rowson S. Maurice Kendall writes in [ 4 ] :- The increasing popularity of the book did a great deal to counteract Yule's feeling of being left behind by modern developments.

He professed to be astonished that the work fulfilled his earlier hope that it would be useful to new generations of students, but he was undoubtedly greatly pleased and comforted. The fourteenth and last edition of Introduction to the Theory of Statistics was written jointly with Maurice Kendall and published in , shortly before Yule's death. The first half of the book deals with descriptive statistics: the theory of attributes, frequency distributions and their characteristics, correlation and regression, and curve fitting.

The second half of the book deals with sampling theory: large and small samples, chi-square, analysis of variance. The last chapters discuss interpolation and graduation, index numbers, and time series. In his later years he applied statistics to literary style and published a book The statistical study of literary vocabulary in His paper Cumulative sampling: a speculation as to what happens in copying manuscripts is described in a review by Feller as follows:- Variations in old manuscripts are to a great extent due to copying errors and these are in turn frequently related to "danger spots" in the outward appearance.

Since the error removes the danger spot, variations due to copying errors will in general be more stable than the original version. The author uses an admittedly greatly oversimplified model of a random game to study the probable development within so-called families of texts. The mathematics is elementary and the interest of the paper lies in conclusions which apparently differ greatly from commonly accepted views.

It is stated that the criterion has been applied to a particular case with results contradicting the philologists' conclusions. Yule did not develop any completely new branches of statistical theory but he took the first steps in many areas which proved important in their further development by later statisticians. Maurice Kendall 's comment in [ 4 ] as to Yule's contribution is, however, very appropriate:- A great deal of Yule's contributions to the advancement of statistics cannot come to light; they reside in the stimulus he gave to his students, the discussions he held with his colleagues on a host of subjects, notably agriculture and demography, and the advice he freely tendered to all who consulted him, for he was always a most approachable man.

The story about Yule learning to fly tells us something of his character. In addition Maurice Kendall tells us in [ 4 ] that Yule was His wide knowledge of many subjects and his love of an apposite story made him the best of companions. His correspondence was a delightful mixture of shop, anecdote, and commentary on things in general As we mentioned above, Yule's health problems began in when he developed heart problems.

He life after this time was lived with a degree of difficulty; climbing stairs became a major undertaking. He acted as if he had little time left to live, spending time tidying up loose ends to his work, yet he lived for twenty years after his heart problems. In fact as the years went by he appeared more prepared to undertake deep research again, and from about onwards he made further major contributions, some of which we mentioned above.

By the late s, however, his health began to deteriorate again and he spent the last two and a half years of his life in nursing homes [ 4 ]
