# Conditionally centered influence curve of contamination type

### Description

Class of conditionally centered (partial) influence
curves of contamination type for average square conditional contamination
neighborhoods; i.e., influence curves *eta* of the form

*eta = A K^(-1) x(Lambda_f - z)min(1, c/|Lambda_f - a|)*

with *K=E x t(x)*, clipping bound *c*, centering constant
*z* and standardizing constant *A*. *Lambda_f* stands for
the L2 derivative of the corresponding error distribution.

### Objects from the Class

Objects can be created by calls of the form `new("Av2CondContIC", ...)`

.
More frequently they are created via the generating function
`Av2CondContIC`

, respectively via the method `generateIC`

.
