when the function argument increases by delta.
Usage
increment.fv(f, delta)
Arguments
f |
Object of class |
delta |
Numeric. The increase in the value of the function argument. |
Details
This command computes the new function
g(x) = f(x+h) - f(x-h)
where h = delta/2. The value of g(x) is
the change in the value of f over an interval of length
delta centred at x.
Value
Another object of class "fv" compatible with X.
