influence |
displays the influence of price determining
parameters on options. It is
using the Black and Scholes formula.
|
|

insert |
inserts an object to the specified position within a list.
|
|
interact |
interact estimates a model with interaction terms.
It is using the marginal integration estimator
with a local polynomial smoother.
For details see Sperlich, Tjostheim, Yang (1997)
|
|
intertest1 |
intertest1 is testing for interaction of x_1 and
x_2 in an additive regression model.
It is looking at the interation estimate and using
wild bootstrap.
For details see Sperlich, Tjostheim, Yang (1997)
|
|
intertest2 |
intertest2 is testing for interaction of x_1 and
x_2 in an additive regression model.
It is looking at the estimate of the mixed derivative
of the joint influence and using wild bootstrap.
For details see Sperlich, Tjostheim, Yang (1997)

|
interval |
transforms the selected variables in a user specified
interval. The transformed variables can replace
the original ones or can be appended on the end of data.x.
the type is automatically set continuous.
|
|
intest |
estimation of the univariate additive functions
in a separable additive model using Nad.Watson,
local linear or local quadratic
|
|
intest1 |
estimation of the univariate additive functions
in a separable additive model using Nad.Wat.
|
|
intest2d |
estimation of a bivariate joint influence function
and its derivatives in a model with possible interaction.
When loc.lin.smoother is chosen you get the function
estimate and the first derivatives in the first and
second direction, when loc.quadr.smoother is chosen
you get the function and the mixed derivative estimate.
