- Probability limit theorems (research papers [1-4], [13], [17,18], [20], [32], see below )
My research in the field of probability limit theorems focuses on the
convergence rate of distributions of sums of independent and identically distributed random
variables (and random vectors) to stable distributions. The main achievement is the so called
"non-uniform bound" for the convergence rate.
- Limit theorems for random processes (research papers [4-12], [14-16], [19], [27], [32], see below)
Main results establish sufficient conditions for the central limit theorem to hold
for stochastically continuous random processes in Skorokhod space D[0,1]
of CADLAG (right continuous and having left limits) functions. The case of
Gaussian limit process (with continuous sample paths) and the case of stochastically continuous
stable limit process (with sample paths having no discontinuities of the second kind) are
treated separately. Conditions are formulated in terms of moments (weak moments in case of
stable limit) of increments of summands (that are stochastically continuous processes with
sample paths in D[0,1]).
- Mathematical statistics: approximation of distributions of non-linear statistics
(research papers [17,18], [20,21], [33], see below)
A new approach is used to study the accuracy of the normal approximation
of M estimators in the case of asymptotically convex score function, see [18].
This approach (based on the law of large numbers for random functions) allows to show a
Berry-Esseen bound under optimal conditions (minimal smoothness condition on the score function
and optimal moment conditions).
Accuracy of the normal approximation of distributions selfnormalized sums is studied in
[17], [20,21]. A general and precise Berry-Esseen type bound for Student's t statistic is
shown in [17] for independent not identically distributed observations. One term Edgeworth
expansion is established in [20,21] under the optimal conditions: finite third moment and
non-lattice distribution of summands.
- Mathematical statistics: approximation of distributions of finite population statistics
(research papers [22-26], [28-31], [34-37], see below)
The papers [22,24, 30,31] develop Hoeffding's decomposition for symmetric
statistics and show one term Edgeworth expansion for distributions of symmetric statistics.
Empirical Edgeworth expansion (based on jackknife estimators of moments defining the expansion)
is constructed in [28,29]. One term Edgeworth expansion and its empirical counterpart is constructed
for Studentized finite population statistics in [34,35].
Stratified samples are considered in [36,37].
Current research
- normal approximation and Edgeworth expansions for distributions of symmetric statistics;
- resampling approximation in finite populations;
- approximations of distributions of combinatorial statistics (sub-graph count).
