چکیده

The central limit theorem says that, provided an estimator fulfills certain weak conditions, then, for reasonable sample sizes, the sampling distribution of the estimator converges to normality. We propose a procedure to find out what a “reasonably large sample size” is. The procedure is based on the properties of Gini’s mean difference decomposition. We show the results of implementations of the procedure from simulated datasets and data from the German Socio‐economic Panel.

I I the Invariance Principle for One - Sample Rank - Order Statisticsi

Analogous to the Donsker theorem on partial cumulative sums of independent random variables, for one-sample rank-order statistics, weak convergence to Brownian motion processes is studied here. This yields a simple proof of the asymptotic normality of the related rank statistics for random sample sizes. Analogous to the Donsker theorem on partial cumulative sums of independent random variables,...

Semi-Nonparametric Methods for Detecting Latent Non-normality: A Fusion of Latent Trait and Ordered Latent Class Modeling.

Ordered latent class analysis (OLCA) can be used to approximate unidimensional latent distributions. The main objective of this study is to evaluate the method of OLCA in detecting non-normality of an unobserved continuous variable (i.e., a common factor) used to explain the covariation between dichotomous item-level responses. Using simulation, we compared a model in which probabilities of cla...

A kernel type nonparametric density estimator for decompounding

Given a sample from a discretely observed compound Poisson process we consider estimation of the density of the jump sizes. We propose a kernel type nonparametric density estimator and study its asymptotic properties. Asymptotic expansions of the bias and variance of the estimator are given and pointwise weak consistency and asymptotic normality are established. We also derive the minimax conve...

Some Tests of Symmetry ·e Some Tests of Symmetry

CARL NOBUO YOSHIZAWA. Some Tests of Symmetry. (Under the direction of C.L DAVIS) Three nonparametric tests of symmetry about an unknown value are considered for continuous univariate distributions. Each test statistic is defined as the difference between the sample mean and an estimator of the median. Two of the median estimators are special cases of general quantile estimators which were propo...

Marginal analysis of correlated failure time data with informative cluster sizes.

We consider modeling correlated survival data when cluster sizes may be informative to the outcome of interest based on a within-cluster resampling (WCR) approach and a weighted score function (WSF) method. We derive the large sample properties for the WCR estimators under the Cox proportional hazards model. We establish consistency and asymptotic normality of the regression coefficient estimat...
