Kỹ thuật kiểm định thống kê có thông số (parametric tests) thường đòi hỏi 1 số giả định (assumptions) về dân số được khảo sát, đặc biệt nhất là tính phân phối bình thường, biến số được đo ở thang khoảng (interval) hoặc thang tỉ số (ratio), và mẫu ngẫu nhiên và độc lập.

(BQ) Part 2 book "A handbook of applied statistics in pharmacology" presents the following contents: Non-Parametric tests, cluster analysis, trend tests, dose response relationships, analysis of pathology data, designing an animal experiment in pharmacology and toxicology—randomization, determining sample size, how to select an appropriate statistical tool,...
Linear parametric models of stationary random processes, whether signal or noise, have been found
to be useful in a wide variety of signal processing tasks such as signal detection, estimation, filtering,
Forty years ago there was hardly a ﬁeld called ‘behavioral sciences’. In fact, psychology largely
was the behavioral sciences, with some help from group theory in sociology and decision-
making in economics. Now, of course, psychology has expanded and developed in a myriad
of ways, to the point where ‘behavioral sciences’ is often the more useful term. Physiological
psychology has become neuroscience, covering areas not previously part of psychology.
Decision-making has become decision science, involving people from economics, marketing,
and other disciplines.
The study of natural catastrophe models plays an important role in
the prevention and mitigation of disasters. After the occurrence of a nat-
ural disaster, the reconstruction can be ﬁnanced with catastrophe bonds
(CAT bonds) or reinsurance. This paper examines the calibration of a real
parametric CAT bond for earthquakes that was sponsored by the Mexican
government. The calibration of the CAT bond is based on the estimation
of the intensity rate that describes the earthquake process from the two
sides of the contract, the reinsurance and the capital markets, and from the
In this volume I present some examples of line integrals, cf. also Calculus 2b, Functions of Several
Variables. Since my aim also has been to demonstrate some solution strategy I have as far as possible
structured the examples according to the following form
A Awareness, i.e. a short description of what is the problem.
D Decision, i.e. a reflection over what should be done with the problem.
I Implementation, i.e. where all the calculations are made.
C Control, i.e. a test of the result.
This is an ideal form of a general procedure of solution.

Chapter 17 - Hypothesis testing. After studying this chapter you will be able to understand: The nature and logic of hypothesis testing, a statistically significant difference, the six-step hypothesis testing procedure, the differences between parametric and nonparametric tests and when to use each, the factors that influence the selection of an appropriate test of statistical significance, how to interpret the various test statistics.
Since the publication of my book Mathematical Statistics (Shao, 2003), I
have been asked many times for a solution manual to the exercises in my
book. Without doubt, exercises form an important part of a textbook
on mathematical statistics, not only in training students for their research
ability in mathematical statistics but also in presenting many additional
results as complementary material to the main text.
To supplement full scale dynamic testing of vehicle crashworthiness, mathematical models and laboratory tests (such as those using a Hyge sled or a vehicle crash simulator) are frequently employed. The objective of these tests is the prediction of changes in overall safety performance as vehicle structural and occupant restraint parameters are varied. To achieve this objective, it is frequently desirable to characterize vehicle crash pulses such that parametric optimization of the crash performance can be defined.
Chapter 14 MULTIPLE HYPOTHESIS TESTING
Although economic theory generally provides only loose restrictions on the distribution of observable quantities, much econometric work is based on tightly specified parametric models and likelihood based methods of inference.
Chapter 42 RESTRICTIONS OF ECONOMIC NONPARAMETRIC METHODS
Increasingly, it appears that restrictions implied by economic theory provide extremely useful tools for developing nonparametric estimation and testing methods. Unlike parametric methods, in which the functions and distributions in a model are
specified up to a finite dimensional vector
In the first approach, we divide our sample into two groups, based on each of the explanatory
variables in turn, and calculate the median CGAP measure for each group. In some cases
the demarcation between the two groups is clear: For example, economies may be classified
as either an emerging market economy (EME) or not. For continuous variables, we use the
median across the sample to divide the economies into two groups: economies where the
explanatory variable exceeds the median are placed in group 1, and the remainder in group
