ABSTRACT
This chapter explores the adjective 'inadequate' in respect to 'frames' in sample surveys is somewhat vague and not so sharply pointed. It discusses 'Multiple frames' deserve a totally separate treatment. 'Inadequate frames' are quite common phenomena in large-scale surveys. Suppose researchers intend to execute a survey of households in a big province in a country, like a 'state' in USA or a 'state or union territory' in the Indian union. A better course might have prepare a comprehensive frame for those households which incur expenses on hospital treatment of the inmates suffering from one of the three diseases mentioned over a year or more. If researchers cannot start with an adequate frame of households in the villages of a district of a province of interest known to have patients of a specified kind researchers may circumvent the sample selection and estimations along with estimated measures of error in this way with constrained adaptive sampling.
