Derivative Calculation for Maximum Likelihood---III

• As far as your computer program is concerned, one can handle and likelihood with same program.

• They just differ in calculational complexity N.

  In , N is the number of ``bins.''

  In likelihood, N is number of events.

• My old fitting programs

• were designed to interface with either or maximum likelihood.
