Details

Only even functions are allowed as adjustment terms. Also Hermite polynomials must be of degree at least 4 and Cosine of order at least 3. Finally, also checks that order of the terms >1 for half-normal/hazard-rate, as per p.47 of Buckland et al (2001). If incorrect terms are supplied then an error is throw via stop.

Value

Nothing! Just calls stop if something goes wrong.
