A function that relates operating model parameters and parameters of the observation model to relative yield (yield over last 5 years of projection relative to a 'best F' scenario that maximizes yield).

## Arguments

Maximum number of observation variables to examine per MP

- nbins
Number of bins for sampled observation variables used for calculating variability in utility across the sampled range of each parameter

- Ut

- Utnam
