The parameter values supplied with a procedure call must be constants or a variable; a function name cannot be used as a parameter value. Variables can be user-defined or system variables such as@@spid. The following examples demonstrate passing parameter values to the procedureuspGetWhereUsedProd...
The model class reliance of all the p variables can be given as a range of lower and upper bounds of weighted feature importance values. The lower and upper bounds of the model class reliance for each variable can be defined as, \begin{aligned} MAMCR^k= & {} \big [ MAMCR^{k-}, ...
