چکیده

Let W ( ) be either the number of descents or inversions of a permutation 2 Sn. Stein's method is applied to bound the sup-norm distance between the distribution of W and the standard normal distribution. This appears to be the rst use of Stein's method in theory of permutation statistics. The construction of an exchangeable pair (W;W 0) used in Stein's method is non-trivial and may be of independent interest. 2

Stein ’ s Method Proof of the Asymptotic Normality of Descents and Inversions in the Symmetric Group By Jason

Let W (π) be either the number of descents or inversions of a permutation π ∈ Sn. Stein’s method is applied to bound the sup-norm distance between the distribution of W and the standard normal distribution. This appears to be the first use of Stein’s method in theory of permutation statistics. The construction of an exchangeable pair (W,W ) used in Stein’s method is non-trivial and may be of in...

Some Asymptotic Results of Kernel Density Estimator in Length-Biased Sampling

In this paper, we prove the strong uniform consistency and asymptotic normality of the kernel density estimator proposed by Jones [12] for length-biased data.The approach is based on the invariance principle for the empirical processes proved by Horváth [10]. All simulations are drawn for different cases to demonstrate both, consistency and asymptotic normality and the method is illustrated by ...

The Distribution of Descents in Fixed Conjugacy Classes of the Symmetric

The distribution of descents in a xed conjugacy class of Sn is studied and it is shown that its moments have a remarkable property. This is proven two ways: one way via generating functions and another way via a combinatorial algorithm. This leads to an asymptotic normality theorem for the number of descents and major index in conjugacy classes of Sn with large cycles. 3

Asymptotic Behaviors of Nearest Neighbor Kernel Density Estimator in Left-truncated Data

Kernel density estimators are the basic tools for density estimation in non-parametric statistics.  The k-nearest neighbor kernel estimators represent a special form of kernel density estimators, in  which  the  bandwidth  is varied depending on the location of the sample points. In this paper‎, we  initially introduce the k-nearest neighbor kernel density estimator in the random left-truncatio...

The eccentric connectivity index of bucket recursive trees

If $G$ is a connected graph with vertex set $V$, then the eccentric connectivity index of $G$, $xi^c(G)$, is defined as $sum_{vin V(G)}deg(v)ecc(v)$ where $deg(v)$ is the degree of a vertex $v$ and $ecc(v)$ is its eccentricity. In this paper we show some convergence in probability and an asymptotic normality based on this index in random bucket recursive trees.
