Statistical investigations

From 8 to 30 pounds [or 120 leaves, if foliage (4)] of the field sample are used penetration samples are dissected or otherwise suitably treated so as to afford several pounds of the desired anatomical portion of the field sample. [The size of the field sample and its method of collection vary tremendously for different materials—e.g., olives vs. alfalfa hay. These two parameters are under statistical investigation, but the paucity of reliable and sufficiently extensive data precludes formal publication of field sampling and processing techniques for materials other than leaves 4). A manual of processing procedure (5) has been mimeographed for guidance of personnel, based upon empirical observations as data are accumulated, it will be revised and expanded periodically. ]... 

The R D lab, then, would benefit from LIMS technology exhibiting high flexibility, the ability to structure large empirical data bases, and the ability to support scientific and statistical investigations.

The optimum time for a sample to be kept under load is 5 seconds according to most authors. It has been shown by way of statistical investigation that as the static loading time is lengthened, a gradual decline...

Some errors are unavoidable in impact sensitivity tests like the drop hammer test and drop ball test Important questions involve the precision and accuracy of acquired results. During the World War II in U.S.A., statistical investigations on drop hammer tests were carried out mainly by Professor Dixon 211 at the Bruceton Laboratory to achieve greater accuracy in determining impact sensitivity with the fewest trials. 

Doubtless it is correct that even one is one too many, and really one must go even farther than that even those measures of Third Reich persecution which did not result in outright deaths were in every respect unacceptable. But this is not a vahd argument against the statistical investigation of the whether and how of the destruction of the Jews, and for three reasons. 

This is how editor W. Benz summarizes the statistical investigations of his seventeen co-authors, each of whom focused on one nation that had been either occupied by or allied with the Third Reich. But it must be pointed out that... 

If the data are stored on floppy-discs, they are always available for further statistical investigations concerned with reproducibility, ring experiments or survey statistics, without taking up storage space. 

The example shown above, introduces the necessity for a statistical investigation of the response surface near its great curvature domain. We can establish the proximity of the great curvature domain of the response surface by means of more complementary experiments in the centre of the experimental plan (xj = 0,X2 = 0,...Xij = 0). In these conditions, we can compute y, which, together with Pq (computed by the expression recommended for a factorial experiment... 

The results of statistical investigations of the orbital parameters of nearly parabolic comets led Oort to the interpretation that a cloud of about 10 comets... 

The statistical investigation of a model begins with the estimation of its parameters from observations. Chapters 4 and 5 give some background for this step. For single-response observations with independent normal error distributions and given relative precisions, Bayes theorem leads to the famous method of least squares. Multiresponse observations need more detailed treatment, to be discussed in Chapter 7.

Consequently, statistical investigations of descriptors should be performed on vectors containing at least 128 components and training sets containing at least 50 compounds. 

When applied together with a LC-MS analysis, IR mapping allows a statistical investigation and thus a rapid quality control of the library synthesized by the split-and-combine method. The decisive advantage of this technique is that 1R analysis, in contrast to mass spectrometry, can be carried out without destruction of the sample, and with spatial resolution. 

These observations are supported by statistic investigations from the US [6]. Here it was ascertained that the presence of VC and with that the dechlorination tends to result in the formation of shorter CAH plumes [7]. 

The magnitude and orientation of dipole vectors may easily be studied by statistical methods (see 12.4.2.3). Higher moments are less easily employed in both lattice energy calculations and statistical investigations.
