Some remarks on the existence of optimal quantizers

Abaya, Efren F.; Wise, Gary L. - In: Statistics & Probability Letters 2 (1984) 6, pp. 349-351

Necessary and sufficient conditions are given for the existence of optimal k-dimensional quantizers that minimize a distortion measure E{W(X)C(X - Q(X))}. An example is given in which a globally optimal quantizer does not exist.
