My Basis Function
!MBF
!MBF mbf(v,n) f [ !SKIP k ]
specified on a separate line
after the datafile line
predefines the model term
mbf(v,n)
as a set of n
covariates
indexed by the data values in variable v.
MBF stands for My Basis Function and uses the same mechanism as
the
leg(), pol()
and
spl()
model functions
but with covariates supplied by the user.
The file f should contain 1+n fields where the first field
contains the values which are in the data variable or at which prediction
is required, and the remaining n fields define the
corresponding covariate values.
!SKIP k
is an optional qualifier
which requests the first k lines of the file be ignored.
