This thesis addresses the problem of deciding whether or not
two disjoint random samples that are fitted by the same regression
equation emanate from the same parental population. Two situations
are considered. The first situation is where the two disjoint samples
are individually fitted with the regression equation. The second...
In 1962 a large amount of data was collected in an effort to
establish the existence of subsurface ocean currents off the coast of
Oregon. The presence of several phenomena, including tides and
measurement errors not directly associated with the hypothetical
currents, complicates the interpretation of the data and the...
When stratification is employed to reduce the variance of an
estimate of the population mean, and the population does not possess an
a priori partitioning, the degree of reduction provided is affected by
the method of allocation, by the number of strata, and by the choice of
the stratum boundaries....
This thesis presents a table of dependent, mixed variables
and attributes double sampling plans, where the standard deviation
of the quality characteristic is assumed to be known, and the acceptance
number is zero for the attributes portion of the plans.
The table gives sampling plans for ten ranges of lot...
Consider the estimation of the category proportions in a
multinomial population from a sample which is "censored" in the
sense that under an appropriate, unknown permutation of the sample
categories, the population proportions are all known. We are considering
the estimation of an ordered set of sample proportions, known
except...
This thesis is concerned with the detailed derivation
of Sheppard's Correction Formula relating the true to the
raw moments by the use of Euler-MacLaurin formula. Special
moment relationships have been derived using different
special functions, whose application is made to derive correction
formula for the semi-invariants. Special investigation
is carried...
Consider the c- sample testing problem with null hypothesis H[subscript]o : F₁(x) = ... = F[subscript]c(x), where F[subscript]j(x), j = 1 ..., c, represent
absolutely continuous distribution functions for failure distributions.
Furthermore, consider arbitrarily (right) censored samples, which
may arise from putting the (censored) experimental units on test at
different...
