Burt matrix
WebBurt (1953) criticized their quantitative analysis of "qualitative" table data in a journal article. To circumvent this problem, Burt developed MCA (homogeneity analysis) of a binary indicator (or Burt) matrix. In response to Burt's article (1953), Guttman reports that optimal scaling is mathematically equivalent to factor analysis. WebSep 1, 2005 · The code, burt, is a very simple program that calculates the Burt matrix using the code indicator. The input parameter is the table, N, and the output consists only of the Burt matrix. 3.3 Performing Correspondence Analysis The code outlined in corr performs correspondence analysis for a two-way or three-way contingency table.
