Table 10-3. FRCST Menu Labels
Menu Label Description
list name for x-variable
list name for y-variable These specify the two lists of data to be
compared. Also used for estimations:store
x and estimate y, or vice-versa.
 is
the menu label for an unnamed current list.
 * Calculates the correlation coefficient, a
number between
－1 and ＋1 that
measures how closely the x,y data points
match the calculated curve.
 * Calculates M. For the linear model, this is
the slope.
Calculates B. For the linear model, this is
the y-intercept.
 *

 Displays a choice of the four curve-fitting
models:
 ,  ,  , and  .
 Calculates the weighted mean of the
x-values using the weights in the y-list.
 Calculates the standard deviation of a set
of x-values grouped by frequencies
specified in the y-list.
The number of items in either list.


 Sum of items in x-list.
 Sum of items in y-list.
 Sum of squares of items in x-list.
 Sum of squares of items in y-list.
 Sum of products of items in x- and y-lists.
* For the non-linear models, the calculation uses the transformed data values.
