The global null hypothesis is that all of the local null hypotheses are true, so that failure to reject the global null hypothesis implies that significant results have not been detected anywhere in the field of individual local tests.
Livezey and Chen (1983) also suggest estimating the frequency distribution for numbers of locally significant tests using Monte Carlo methods (i.e., randomly resampling the available data in a manner consistent with the global null hypothesis; e.g., Mielke et al.
(c) the family F may evolve into a totally geodesic null hypersurface (H,[gamma], l) only if [[lambda].sub.u] [right arrow] 0 on H and then = [[theta].sub.(l)] on H.
Now we know that a null hypersurface of a semi-Riemannian manifold has zero expansion if and onlyifitistotallygeodesicso (c) holds which completes the proof.
The recovery of one null due to 7th sensor failure and SSF to its original position [[theta].sub.1] = 19.93[degrees] is shown in Figures 4 and 5.
From Figure 14 it is clear that its SLL increases and nulls are damaged and also lose null depth.
A software programme (available on request) was written for the purpose of calculating LRs in cases where null alleles could be segregating.
where [[theta].sub.i] for i = 1, 2, ..., [M.sub.0] is the direction of null. Our objective is to optimize the squared weighting error subject to the constraint that
Position vector of a simple closed null W-curve in Minkowski space [E.sup.3.sub.1] can be composed by the components (7), (8) and (9); or (10), (11) and (12) according to singature of the torsion.
Tomioka (2003) proposes that null subjects occur in languages that allow (robust) bare NP arguments.
You could use a Null value in this field although it is recommended to use a true value such as "N/A" or "Not Applicable", making information clearer to the user.
