increase by a constant for each examination seriee. A propoaed tape
configuration s-1ded to the present computer would allow for the elimination
of certain administrative responsibil.ities prior to the administration
of each examination (elimination of !UV,PZRS 524 which contains
biographical information on each candidate). A raster tape file cotttinuoualy
updat,ed by NEC in conjunction with the collection of certain
infonnntion directly from the answer card would eventually eliminate
the necessity for ordering examinaticns and they could be sent out
automatically by name vhen each candidate becarocs eligible, as indCcatRd
by the file maintained by NEG.
Actuarial Longevity Prediction Study
Since the literature only covers conventional statistical approaches
to prediction, such as regression analysis or multiple regression, and in
some cases the application of the Poisaon distribution or the negative
bi-nomial, raw data was acquired to experimentally determine the fcaafbility
of utilizing the actuarial approach in predicting longevity. F31vfdence
to data indicates that this approach will eventually be ctilized in
certain areaa of prediction as a routine technique, To fully appreciate
the success attained by this approach, addifional comparison studies
between various predictive techniques will be conducted aa to the eventual
superiority of one in terms of minimizing error, fewer assumptions, time
clement, and the final extrapolations from the data that are poaeible.
Class Scheduling Project
A atudent, teacher, and class scheduling project was cmglcted by
hand baaed on raw data (N=2000) for a single school, The application
of resulta will eventually be duplicated by a computer program and the
two aete of results will be analyzed for comparibility. The project
will then be extended for application to the CNARESTRA problem (N-35,000)
which will Involve a series of schools located geographically in various
parts of the country and eventually encompass the mobility of atudenta
from one area to another. Complete coordination will be poacible between
the transportation, teacher, student, school, classroom, time sequence,
and course information factors, all will be in one co;aplete computer
program.
Differential Weights of Final Multiple
The final multiple acore is composed of five individual factor
scores which are a-d on the basis of a simple weigLting formula.
Each factor has a designated ideal contribution to the overall variance,
but the actual or real factor contribution IZWIY and does obviously vary
from this standard. A study was implemented to determine the empirical
interaction of the five factors making up rhe total composite of the
multiple variance of passing candidates in selected critfcal ratea frclm
previous examination series. The results indicated that the factor
