Isotoner Embroidered Ballerina Women's Slippers.
Has debuted a line of mattress toppers employing the Isotonic ErgoSmart trademarked technology.
The Olympics may inspire a record-breaking sales season for isotonic sports drinks in Atlanta this summer.
But Totes/Isotoner in Cincinnati thinks it has a new twist that could put more of them in the hands of a new generation.

The isotonic pro jection, on the other hand, only lives on [0, ∞), and follows the steep increase of the real hazard to the right of 2.0, whereas it only locally corrects for the non-monotonicity.

It is also of interest to compare the powers of the procedure, based on bootstrapping from a penalized and smoothed version of the hazard, with the powers obtained by just bootstrapping from the isotonic piecewise constant hazard estimate without any smoothing or penalizing.

The general trend is that bootstrapping from the isotonic estimate itself gives more conservative critical values.
