ABSTRACT
This chapter discusses procedures for selection from one-parameter and two-parameter exponential populations, and also some related inference problems. It provides a brief introduction to selection and ranking methodology explaining the salient features. The chapter describes single-stage procedures based on complete as well as Type I, Type II, and randomly censored samples. It deals with selection from two- parameter exponential populations in terms of their guaranteed lifetimes. The chapter examines single-stage, two-stage, three-stage, and purely sequential procedures. It suggests comparison of exponential guaranteed lifetimes with a standard or a control. The chapter is concerned with estimation concerning selected populations. Selection and ranking problems have generally been studied by using either the indifference zone (IZ) formulation of R. E. Bechhofer or the subset selection (SS) formulation due mainly to S. S. Gupta. There are several variations and generalizations of the basic goal in both IZ and SS formulations.
