igcond(t, k, eta)

igcondinv(p, k, eta, mxiter = 40, eps = 1e-06, bd = 5)

`t`	Vector of values to evaluate the assistant function at, >=1.
`k`	Single numeric, greater than 1.
`eta`	eta parameter. Vectorized to match `t` and `p`.
`p`	Vector of values to evaluate the inverse assistant function at, in [0,1].
`mxiter`	Maximum number of iterations to run the Newton-Raphson algorithm for.
`eps`	The Newton-Raphson algorithm is stopped if all step sizes are below this value.
`bd`	Largest acceptable step size in the Newton-Raphson algorithm; steps larger than this will be reduced.
