This report provides empirical results of attempts to |
|
achieve consistency of estimates between two National |
|
Center for Education Statistics (NCES) surveys, the 1993- |
|
94 Private School Survey (PSS) and the Schools and |
|
Staffing Survey (SASS). Comparisons are made among |
|
statistical and computational procedures that may achieve |
|
the desired consistency between estimates. An overview |
|
describes the problem of consistency and why it matters. |
|
Sections 2 through 4 of this report explore the |
|
adjustment alternatives, with the main methods described |
|
in Section 2. These include the modified generalized |
|
least squares (GLS) approach evaluated in a pilot study |
|
and the variation of the GLS proposed by I. Olkin (1958). |
|
The third section presents results for nine independent |
|
applications for each category of the nine-category NCES |
|
typology for private schools. Section 4 presents |
|
conclusions, summarizing the work done, and making some |
|
recommendations. The new Olkin approach represents some |
|
improvements on the GLS approach previously tested, but |
|
results are not as encouraging as had been hoped. Section |
|
5 presents references, and the algorithms used are |
|
illustrated in an appendix (Section 6). (Contains 36 |
|
tables, 40 figures, and 49 references.) (SLD) |
