To limit the probability of erroneously rejecting any of [N.sub.0] = 100 true null hypotheses to the level [[alpha].sub.0] = 0.05, only those tests having p values smaller than [[alpha].sub.Walker] = 0.000513 would be regarded as significant according to this criterion.
(2) will yield relatively few rejections of true null hypotheses, the Walker criterion is quite strict since [[alpha].sub.Walker] [approximately equal to] [[alpha].sub.0] / N, which compromises the sensitivity of the procedure for detecting false null hypotheses.
Now we deal with the question of obtaining a normalized expression for a null normal l of a null hypersurface H [member of] F.
Let F = (([H.sub.u]),([h.sub.u]),([l.sub.u])) be a family of null hypersurfaces of the GRW space-time ([bar.M], [bar.g]) defined by (2) such that F is given by (7) and each of its members ([H.sub.u], [h.sub.u], [l.sub.u]) is conformal to a fixed null hypersurface (H, [gamma], l), where [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] for every parameter value of u.
where 0; for i = 1,2, ...,M0 is the direction of null. Our goal is to optimize the squared weighting error subject to the condition that
After sensor failure the radiation pattern is destroyed, which results in an increase of the SLL and displacement of null positions.
The effect of allowing for the possible presence of a null allele
Paternity test trios (mother, child and alleged father) in which a vWA null allele appeared to be segregating were selected.
The fitness function depends on the mean square error (MSE) between the desired array factor and estimated array factor given in Equation (6) and the null constraint error given in Equation (7).
For an arbitrary array, to put a null at a given angle [[theta].sub.i], we need [24],
Several criticisms of the classical approach are that the null hypothesis under consideration may not be plausible, future evaluation may not be done once the hypothesis is rejected or fails to be rejected, and that prior information (probability) is not considered.
Let [alpha] be a null Cartan curve in [E.sup.4.sub.1] Then [alpha] is congruent to an osculating curve of the first kind if and only if its third curvature [[kappa].sub.3](s) is equal to zero for each s.
Let us suppose [phi] = [phi](s) be a null W-curve in the space [E.sup.3.sub.1].
Speas (1994) proposed that the expression or otherwise of null subjects is determined by whether the [??] features in [I.sup.O] have some specification.
You may also have a case for a null value if you are working in a database and none of its values has a record.
