The AppLication of X~2Distance Coefficient in the Method of Reduction of Dimensionnality through EXtreme Point Analgsis of High-Dimensioned Sample Points
Its essential idea is:①、From G1,G2,…,Gk choose a group Gα1,it can be satisfied that Gα1 can distinguish each sample to a greatest extend, i.e., using the existing discriminate methods (choosing index and not-choosing index) to judge each sample whether in Gα1 or not in Gα1 so as to maximize the correct rates of back substitution.
Let random variable x obey exponential distribution f(x,θ)=1θ e -xθ x≥0 0 x<0 X (1) ≤X (2) ≤ … ≤X (r ) be replacement data based on censored sample,and n be sample size (r≤n ).
The theorem is then used to characterize a class of entire functions that can be reconstructed from their sample values at the points tn = an + b if n = 0, 1, 2, ...

An antibiotic producing strain Streptomyces violaceusniger was isolated from soil sample, characterized and studied for antibacterial and antifungal activity profile.
The parametric methods of significance test commonly used in textile industries are based on the assumption that the parent population were distributed normally or in some other definite form. Yet in textile industries exact informations about the population distribution are hardly accessible to us. Hence a test independent of the nature of the population distribution is needed in these industries. In this paper we first discuss a non-parametric method of testing whether two samples of machine parts a...
The method for correct use of the Chokoff's fiber sorter is discussed. It was found that this sorter gives the same result as the Webb's concerning the cotton fiber length. The test results under different conditions are compared and the conditions for satisfactory results are described. A standard sample of 25.4 mm. length (mode, tested by Webb's sorter) is used in the test. An alternative method is suggested for calculating the fiber length distribution frequencies, For this purpose a special slide ...
In this papér, it is discussed from the statistical points of view the two main topics related to classifying the grades of thickness irregularity of cotton yarn, namely: (1) the method for setting the grades intervals, and (2) the method for classifying the sampled population into one of the grades previously defined. Concept on the critical values for setting grade intervals is introduced and discussed, the errors in classifying the sampled population due to thsee values are also intesvigated....
