This function outputs the nth derivative of a histogram smooth.
get.deriv.smooth.hist(x, coefs, knots, deg = 4, deriv.deg = 1)| x | values from smooth_hist |
|---|---|
| coefs | Coefficients from GAM from smooth_hist |
| knots | Number of knots fit for GAM |
| deg | Degree of polynomials |
| deriv.deg | The degree of the derivative. |
