HYPOTHESIS TESTING

Australian Critical Care, 2009
This article presents a statistical approach called hypothesis testing. This is based upon information collected from a random sample following which results are generalised for the entire population. Some general concepts and terminology of the methodology are briefly described including statistical hypotheses, types of errors, one- or two-tailed ...

Testing the Convergence Hypothesis: A Comment [PDF]

open access: possibleReview of Economics and Statistics, 1997
In a recent paper Lichtenberg (1994) proposes a test of the convergence hypothesis that the variance of productivity across countries decreases over time. He argues that the ratio of the variance in the first period to that in the last period of the time series is F-distributed bur overlooks the dependency between these two variances. As a consequence,

Hypothesis Testing

Clinical Nurse Specialist, 1996
Hypothesis testing is the process of making a choice between two conflicting hypotheses. The null hypothesis, H0, is a statistical proposition stating that there is no significant difference between a hypothesized value of a population parameter and its value estimated from a sample drawn from that population. The alternative hypothesis, H1 or Ha, is a

Test of the neutrality hypothesis

Annals of Human Genetics, 1976
*Note. Dr Price died unexpectedly in January 1976 while he was working on the Kimura neutral gene hypothesis. He had been investigating methods of programming and using a significance teat, due to W. J. Ewens (1972), and had been applying them to the date on enzyme polymorphisms collected in the Galton Laboratory.

Hypothesis Testing: Methodology and Limitations

2001
A test is a statistical procedure to obtain a statement on the truth or falsity of a proposition, on the basis of empirical evidence. After a brief historical account, attention is given to the contrasting approaches of R.A. Fisher's significance tests and J.Neyman and E. Pearson's tests of a null against an alternative hypothesis.

Hypothesis Testing

2003
Abstract The previous chapter described confidence intervals, which provide a fundamental strategy for making inferences about population measures of location such as the population mean μ and the population median. About a century after Laplace’s ground breaking work on sampling distributions, a new set of tools was developed for making

A Test of Lippold's Hypothesis

Archives of Neurology, 1973
Direct experimental evidence bearing on the hypothesis that the alpha rhythm is generated by tremor of the extraocular muscles which modulates the corneoretinal potential is presented. The average percent of alpha was continuously measured on a cat during ketamine hydrochloride anesthesia and decamethonium bromide paralysis. Alpha production increased,

Testing the Convergence Hypothesis

The Review of Economics and Statistics, 1994
The authors show that, contrary to the beliefs of some previous analysts of international economic growth, the hypotheses of convergence and of mean-reversion are not equivalent. Under some assumptions, the rate of convergence is independent of the degree of mean-reversion; under other assumptions, mean-reversion is a necessary, but not a sufficient ...
