decrstep20(k)A numeric.
iteration number.
parameter for the decreasing step function after which the step decreases.
Christophe Dutang
The decrstep function is a decreasing step serie such that decrstep(k)
equals to decrstep5, decrstep10, decrstep20 are just wrappers of
decrstep.
The purestep function implements a constant step serie equaled to 1.
