Hendra virus (Hendra henipavirus) is a zoonotic virus found solely in Australia. First isolated in 1994, the virus has since been connected to numerous outbreaks of disease in domestic horses and seven human cases. Hendra virus belongs to the genus Henipavirus, which also contains the zoonotic Nipah virus.
In clinical medicine, antibiotics are most frequently prescribed on the basis of a person's symptoms and medical guidelines.This method of antibiotic selection is called empiric therapy, [1] and it is based on knowledge about what bacteria cause an infection, and to what antibiotics bacteria may be sensitive or resistant.

A diagnosis of exclusion or by exclusion (per exclusionem) is a diagnosis of a medical condition reached by a process of elimination, which may be necessary if presence cannot be established with complete confidence from history, examination or testing.
If the model is overidentified, there is information available which may be used to test this assumption. The most common test of these overidentifying restrictions, called the Sargan–Hansen test, is based on the observation that the residuals should be uncorrelated with the set of exogenous variables if the instruments are truly exogenous. [22]
Kinetic exclusion assay have also been applied for concentration immunoassay, where it has proven capable of providing the maximum theoretical, K d limited, sensitivity. [ 28 ] [ 29 ] An example of this technique has been employed for sensitive detection of environmental contaminants i n near real-time.
The Sargan test is based on the assumption that model parameters are identified via a priori restrictions on the coefficients, and tests the validity of over-identifying restrictions. The test statistic can be computed from residuals from instrumental variables regression by constructing a quadratic form based on the cross-product of the ...
The Kruskal–Wallis test, from which the Scheirer–Ray–Hare test is derived, serves in contrast to this to investigate the influence of exactly one factor on the measured variable. A non-parametric test comparing exactly two unpaired samples is the Wilcoxon–Mann–Whitney test.
The first type is testing the multiple exclusion restrictions, namely, testing = = [;]. If the unrestricted MLE can be easily computed, it is convenient to use the Wald test [2] whose test statistic is constructed as:
