Viewing analysis results in the Sheet tab Data worksheet

After executing a new formula, a new column of data, containing the results is added to the Data
worksheet of the Sheet tab. See the example in
box was edited to replace a prior version, the corresponding Data worksheet column updates to
reflect the changes.

of the Sheet tab (in column D)
In some cases, a results column contains only a single value. Suppose, for example, that you also
added a formula to find the regression slope for the data as illustrated in
Figure 6-366
Added linear regression slope formula for the plateau
Then after executing the added slope formula, a fifth column containing only a single number (the
slope of the linear regression curve) is added to the Data worksheet of the Sheet tab. See
Figure 6-367.

After some Formulator calculations, you may see one or more instances of the #REF
notation in a column, instead of a number. #REF in a cell indicates that a valid value
could not be calculated. This occurs when a Formulator function needs multiple rows
as arguments, when a calculated value is out of range, when a divide by zero is
attempted, and so on.
For example, each result of the DIFF function is a difference coefficient that is calculated
