Finally, the two radio buttons on the right determine whether to<br />

draw the graph in terms of utilities or in terms of measure levels.<br />

The "Show Measure Levels" button is only enabled if you have<br />

selected a measure from the list above it. When you click "OK,"<br />

LDW will display a graph like the one shown in Figure 8-38.<br />

Figure 8-41. Example of Results::Alternative Uncertainty Graph option.<br />

In the figure, the X-axis represents the range of levels or utilities<br />

that were observed in the Monte Carlo simulation for the<br />

alternative on the active measure or goal. The scale at the left of<br />

the graph is probability and is associated with the blue line. each<br />

point on the line indicates the probability that a simulation trial<br />

will be less than or equal to the utility or level below the point.<br />

The scale on the right represents the number of simulation trials<br />

that were done. It is associated with the yellow bars at the bottom<br />

of the graph. The length of each bar is proportional to the number<br />

of simulation trials that resulted in a level or utility within the<br />

range spanned by the bar.<br />

Compare Alternatives<br />

The compare alternatives option lets you view a detailed<br />

comparison of the differences between two alternatives.<br />
