low |
a constant to define the desirability function for |

the scaling factor for |
x |
a set of input values |
d |
a set of desirabilites between zero and one (inclusive) that match the length of |

The functions dMax
, dMin
, dTarget
ande dOverall
are the basic equations used by Derringer and Suich (1980). dBox
is a simple step funciton between two points. dArb
can be used to create other shapes that do not fall into the other funcional forms. See the package vignette or the references for more details
a list. Common values are:
tol |
the value specified by the |
call |
the origianl function call |
