Specify a value between
0
and
1
to indicate the cumulative proportion of variation to be explained by the
principal components
. The proportion entered here determines the number of principal components used to adjust the
association
tests.
If you want to directly specify the number of components, enter a
0
in this field. The value entered in the
Maximum Number of Principal Components
field is then used.
If no
Trait Variable
s
are specified, this value is used for determining how many principal components to include in the Merged PCA Output Data Set, if it is created.
Note
: This option is enabled only when no
PCA Data Set
is specified.
