Thomson, Godfrey Hilton, Sir, 1881-1955 (psychologist and Bell Professor of Education, University of Edinburgh)
Found in 49 Collections and/or Records:
Thomson asks Ledermann whether the back estimates using the Hotelling method or Bartlett-Thurstone method are best. He has added a short post script at the end of his letter the next day stating M S Bartlett's method is best.
He refers to a geometrical discussion of Bartlett's form of estimation which he originally sent with the letter for Ledermann's comments. This has not survived in the collection.
Also includes a manuscript, numbered 17a (37) which Thomson sets a problem for Ledermann, asking him in his letter if he can provide a proof.
He discusses orthogonal projection, estimation of regression, the selection formulae, and how these can be seen as one; as well as the division of factorial analysis after selection into two parts.
