The Investment analysis adds new input at the bottom of
the tape and runs the expressions from top to bottom. The Investment
analysis uses the 10th percentile, the mode, and the 90th percentile
of the last line on the calculator tape as the low, likely, and high
estimates for the model. To see all values, hover the mouse pointer
over the result value on the paper tape.
By default, if the tape contains no errors, the calculator
automatically recalculates the simulation values and graphs the NPV
results for up to 10,000 samples. When parse errors occur or when
the simulation fails because of undefined variables, the calculator
displays a red "i" near the result field. To get more information
about an error, move the mouse pointer over the “i. To manually control
the simulation, select or clear

results. You can delete a tape, and change the position
of an item using up and down arrows.
To create a smoother NPV curve,
select larger sample sizes from the drop-down menu.
