Table 2.

Illustration of linear transformations using Eq. 2.

	Steps 1 and 2 product scale mean result (n = 104)	Steps 1 and 2 product type scale mean result (n = 9)	Mean turnover per product used in steps 3 and 4	Total turnover used in steps 3 and 4
Expert 1	1.8	–	1.80	187.2
Expert 2	2.1	–	2.10	218.4
Expert 3	–	23	1.99	207
Expert 4	–	24.5	2.12	220.5

Experts 1 and 2 choose to specify turnover per product, resulting in a location parameter on the product scale. Experts 3 and 4 choose to specify turnover per product type, resulting in a location parameter on the product type scale. In steps 3 and 4 we can use either the location parameter on the total turnover scale or the mean turnover scale for experts to provide a reasonable lower and upper bound. All experts’ elicited location parameters can be transformed to both scales.
