Factor Pattern and Factor Correlations for Thurstone's 20 hypothetical box attributes.

Description

Factor Pattern and Factor Correlations for Thurstone's 20 hypothetical box attributes.

Usage

data(ThurstoneBox20)

Format

This is a list containing the Loadings (original factor pattern) and Phi matrix (factor correlation matrix) from Thurstone's 20 Box problem (Thurstone, 1940, p. 227). The original 20-variable Box problem contains measurements on the following score functions of box length (x), width (y), and height (z). Box20 variables:

  1. x^2

  2. y^2

  3. z^2

  4. xy

  5. xz

  6. yz

  7. sqrt(x^2 + y^2)

  8. sqrt(x^2 + z^2)

  9. sqrt(y^2 + z^2)

  10. 2x + 2y

  11. 2x + 2z

  12. 2y + 2z

  13. log(x)

  14. log(y)

  15. log(z)

  16. xyz

  17. sqrt(x^2 + y^2 + z^2)

  18. exp(x)

  19. exp(y)

  20. exp(z)

Details

Two data sets have been described in the literature as Thurstone's Box Data (or Thurstone's Box Problem). The first consists of 20 measurements on a set of 20 hypothetical boxes (i.e., Thurstone made up the data). Those data are available in Box20.
