fftrees_ffttowords
provides a verbal description
of tree definition (as defined in an FFTrees
object).
Thus, fftrees_ffttowords
translates an abstract FFT definition
into natural language output.
fftrees_ffttowords
is the complement function to
fftrees_wordstofftrees
, which parses a verbal description
of an FFT into the abstract tree definition of an FFTrees
object.
The final sentence (or tree node) of the FFT's description
always predicts positive criterion values (i.e., TRUE
instances) first,
before predicting negative criterion values (i.e., FALSE
instances).
Note that this may require a reversal of exit directions,
if the final cue predicted FALSE
instances.
Note that the cue directions and thresholds computed by FFTrees
always predict positive criterion values (i.e., TRUE
or signal,
rather than FALSE
or noise).
Using these thresholds for negative exits (i.e., for predicting instances of
FALSE
or noise) usually requires a reversal (e.g., negating cue direction).
fftrees_ffttowords(x = NULL, mydata = "train", digits = 2)
A modified FFTrees
object x
with
x$trees$inwords
containing a list of string vectors.
An FFTrees
object created with FFTrees
.
The type of data to which a tree is being applied (as character string "train" or "test").
Default: mydata = "train"
.
How many digits to round numeric values (as integer)?
