Related dimension variables
and measurement items are as follows:
These product properties usually depend on a large number of variables, including composition variables, process variables, and dimension variables.
Material properties or product properties depend on composition variables, process variables, and dimension variables, as summarized in Figure 1.
Material properties or product properties depend on composition variables, process variables and dimension variables, as summarized in figure 2.
One would like to determine the best values of composition variables (or feed characteristics), process variables and/or dimension variables such that the resulting material properties or product properties will be within desired limits.
Model 2 shows that with the inclusion of all the culturalcognitive dimension variables
, the R-squared remains almost constant.
The cultural dimension variables have been measured on quasi-interval (Likert) scales.
It should be noted that the three regression models were run with all four of the cultural dimension variables. This was done to establish control over the effects of the other independent variables (Lewis-Beck, 1980) while minimizing the error variance due to correlations among the variables.
It is easy for the designer to use a close tolerance on features to reduce part dimension variables
; however the part cost increases dramatically as tolerances are reduced.
or constraints to changes in the dimension variables
; and the
In that way, all dimension variables
have the same weight and less overfitting problems arise since the degree of freedom in the correlation analysis is increased.
Often process variables and dimension variables
are also taken into account.
