Description: Subject: Statistical Signal Processing. Scope: Radiophysics. We consider the statistical criterion of Student (t-test), a truncated-prednazna to test the hypothesis of equality of average values of two samples of ma-logo, each of which has a normal distribution law with identical Scientifical variance.

Description: Comparison of two survival curves can be done using a statistical hypothesis test called the log rank test. It is used to test the null hypothesis that there is no difference between the population survival curves (i.e. the probability of an event occurring at any time point is the same for each population).

Description: This paper presents a hybrid framework of feature extraction and hidden Markov modeling (HMM) for two-dimensional pattern recognition. Importantly, we explore a new discriminative training criterion to assure model compactness and discriminability. This criterion is derived from the hypothesis test theory via maximizing the confidence of accepting the hypothesis that observations are from target HMM states rather than competing HMM states. Accordingly, we develop the maximum confidence hidden Markov modeling (MC-HMM) for face recognition.

Description: Shadow detection and removal is an important task when dealing with colour outdoor images. Shadows are
generated by a local and relative absence of light. Shadows are, first of all, a local decrease in the amount of
light that reaches a surface. Secondly, they are a local change in the amount of light rejected by a surface toward
the observer. Most shadow detection and segmentation methods are based on image analysis. However, some
factors will affect the detection result due to the complexity of the circumstances, like water and a low intensity
roof because of the special material as they are easy mistaken as shadows. In this paper we present a hypothesis
test to detect shadows from the images and then energy function concept is used to remove the shadow from the
image.

Description: SWTEST Shapiro-Wilk parametric hypothesis test of composite normality.
[H, pValue, SWstatistic] = SWTEST(X, ALPHA, TAIL) performs
the Shapiro-Wilk test to determine if the null hypothesis of
composite normality is a reasonable assumption regarding the
population distribution of a random sample X. The desired significance
level, ALPHA, is an optional scalar input (default = 0.05).
TAIL indicates the type of test (default = 1).-SWTEST Shapiro-Wilk parametric hypothesis test of composite normality.
