Modelling Time of Day Sustitution Using the Second Moments of Demand.

Time of day (TOD) rates are a commonly used method for peak load pricing of many services. Such services as ; electricity, communications, transportation, shared computer facilities, and computer networks (ie. the Internet), either use, or will use form of TOD pricing. The model presented here provides a method for estimating TOD substitution without the need for rate experiments that have proven to be both costly and limited by sample selection bias problems.
