Viewing Data Numerically
You can view the numerical values of a data set, as well as data points to be
excluded from subsequent fits, with the View Data Set GUI. You open this GUI
by selecting a name in the
Data sets list box of the Data GUI and clicking the
View button. The View Data Set GUI for the ENSO data set is shown below,
followed by a description of its features.
•
Data set — Lists the names of the viewed data set and the associated
variables. The data is displayed graphically below this list.
The index, predictor data (
X), response data (Y), and weights (if imported)
are displayed numerically in the table. If the data contains
Infs or NaNs,
those values are labeled “ignored.” If the data contains complex numbers,
only the real part is displayed.
•
Exclusion rules — Lists all the exclusion rules that are compatible with the
viewed data set. When you select an exclusion rule, the data points marked
for exclusion are grayed in the table, and are identified with an “x” in the
graphical display. To exclude the data points while fitting, you must select
the exclusion rule in the Fitting GUI.
An exclusion rule is compatible with the viewed data set if their lengths are
the same, or if it is created by sectioning only.
