Hypothesis and Hypothesis Testing
Steganalysis of JSteg algorithm using hypothesis testing theory
... This paper investigates the statistical detection of JSteg steganography. The approach is based on a statistical model of discrete cosine transformation (DCT) coefficients challenging the usual assumption that among a ...

Hypothesis Testing of Parameters for Ordinary Linear Circular Regression
... In this section we will apply the results of the hypothesis testing and will use the wind and wave direction data as our examples. Suppose variable X is the observation (directions) measured by radar and ...

On the Distribution of Type II Errors in Hypothesis Testing
... In this section we review Type II errors briefly. A de- tailed discussion of Type II errors (and hypothesis testing in general) can be found in any mathematical statistics text, for example, [2]. We assume ...

Hypothesis testing in Bayesian network meta-analysis
... As a result of an NMA, point estimates with credible intervals of pairwise effects between treatment arms are obtained. In this article, we focus on the issue of testing for superiority or noninferiority between ...

Asymmetric quantum hypothesis testing with Gaussian states
... We consider the asymmetric formulation of quantum hypothesis testing, where two quantum hypotheses have different associated costs. In this problem, the aim is to minimize the probability of false negatives ...

Stochastic Complexity, Histograms and Hypothesis Testing of Homogeneity
... Abstract. Information contained in a sample of quantitative data may be summarized or described by a nonparametric histogram density function. An interesting question is how to construct such a histogram density to ...

Chess Masters' Hypothesis Testing
... People are capable of falsifying their hypotheses. Our experimental results show that chess masters falsified their hypotheses: they thought about how their opponent might refute their plan in their move sequences. Chess ...
