of
unknown values
interpolation
– when the
LOBF
is used to make
predictions
within the
range
of
data
given (you don’t need to
extend
you
LOBF
more)
tends to be
reliable
provided the
LOBF
is
correct
extrapolation
– when the
LOBF
is used to
predict values outside
of the
range
of
values
given (you may need to
extend
your
LOBF
for this).
not always
reliable
as
trends
may
change
values estimated from
extrapolation
are
less reliable
the
further
they are from the range of
data
