An invitation to statistics in Wasserstein space [PDF]
This open access book presents the key aspects of statistics in Wasserstein spaces, i.e. statistics in the space of probability measures when endowed with the geometry of optimal transportation.

Goodness-of-fit tests for imperfect maintenance models based on Martingale residuals, varentropy, and probability integral transform [PDF]
In recent years, various goodness-of-fit tests have been developed to identify the underlying distribution of failure data. In this paper, we extend the application of such tests to evaluate the adequacy of imperfect maintenance models for engineering ...

Fuzzy nonparametric regression based on K-nearest neighbors and the R-neighborhood radius [PDF]
In this paper, we present four nonparametric methods to fit some fuzzy regression models, when both the explanatory and response variables are fuzzy quantities. In this approach, we first introduced a distance between triangular fuzzy numbers.

Probabilistic linear widths of Sobolev space with Jacobi weights on [ − 1 , 1 ] $[-1,1]$
Optimal asymptotic orders of the probabilistic linear ( n , δ ) $(n,\delta)$ -widths of λ n , δ ( W 2 , α , β r , ν , L q , α , β ) $\lambda_{n,\delta }(W^{r}_{2,\alpha,\beta }, \nu,L_{q,\alpha,\beta })$ of the weighted Sobolev space W 2 , α , β r $W_{2,{

Mathematical Methods of Statistics A First Course in Mathematical Statistics [PDF]
THESE two books at once invite comparison with A Maurice Kendall's “Advanced Theory of Statistics” and A. C. Aitken's “Statistical Mathematics”. All four are mathematically flawless, and they all require from the reader some mathematical training and ability, but not to the same extent, nor are they all addressed to quite the same category of ...

Spectral statistics of large dimensional Spearman’s rank correlation matrix and its application
Let Q = (Q1, . . . ,Qn) be a random vector drawn from the uniform distribution on the set of all n! permutations of {1, 2, . . . ,n}. Let Z = (Z1, . . . ,Zn), where Zj is the mean zero variance one random variable obtained by centralizing and normalizing
