Class: cvpartition
Test indices for cross-validation
idx = test(c)
idx = test(c,i)
idx = test(c)
returns the logical vector idx
of
test indices for an object c
of the cvpartition
class
of type 'holdout'
or 'resubstitution'
.
If c.Type
is 'holdout'
, idx
specifies
the observations in the test set.
If c.Type
is 'resubstitution'
, idx
specifies
all observations.
idx = test(c,i)
returns the logical vector idx
of
test indices for repetition i
of an object c
of
the cvpartition
class
of type 'kfold'
or 'leaveout'
.
If c.Type
is 'kfold'
, idx
specifies
the observations in the test set in fold i
.
If c.Type
is 'leaveout'
, idx
specifies
the observation left out at repetition i
.
Identify the test indices in the first fold of a partition of 10 observations for 3-fold cross-validation:
c = cvpartition(10,'kfold',3) c = K-fold cross validation partition N: 10 NumTestSets: 3 TrainSize: 7 6 7 TestSize: 3 4 3 test(c,1) ans = 1 1 0 0 0 0 0 0 1 0
