Learning objectives

Introduce students to the theory of nonparametric estimation through models and examples.

Prerequisites and basic notions

Knowledge of measure theory and probability is assumed.

Program

Introduction to the problem of nonparametric estimation and overview of the course topics:
a. methods of construction of estimators,
b. statistical properties of estimators (convergence and rates of convergence),
c. study of optimality of estimators.
Examples of nonparametric problems and models:
- estimation of a probability density,
- nonparametric regression,
- Gaussian white noise model.
Distances/divergences between probability measures:
- Hellinger and total variation distances,
- Scheffè’s theorem and Le Cam’s inequalities,
- Kullback-Leibler and χ2-divergences,
- link inequalities among distances and divergences.
Estimation of the distribution function: definition of the empirical distribution function and consistency.
Estimation of a probability density:
- definition of the Parzen–Rosenblatt kernel density estimator in the uni- and multidimensional cases, examples of kernels,
- definition of the mean squared error (MSE) of kernel estimators at a point and decomposition into the sum of the variance and the squared bias,
- upper bound on the point-wise variance,
- upper bound on the point-wise bias under regularity conditions on the density and the kernel: definitions of Hölder classes and higher order kernels,
- upper bound on the supremum point-wise MSE of kernel estimators,
- mean integrated squared error (MISE): decomposition into the
sum of the integrated variance and the squared bias,
- control of the variance term,
- control of the bias term on Nikol’ski and Sobolev classes of regular densities, upper bound on the MISE for densities in
Sobolev classes.
Fourier analysis of kernel density estimators:
- preliminary facts on Fourier transforms (FT’s),
- the empirical characteristic function: unbiasedness of the FT for the distribution function, expression of the variance,
- expression of the exact MISE of kernel density estimators,
- control of the bias term over Sobolev classes of densities,
- discussion of the local condition around zero on the FT of the
kernel.
Nonparametric regression:
- nonparametric regression with fixed or random design,
- nonparametric regression with random design and the Nadaraya-Watson (N-W) estimator,
- derivation of the expression of the N-W estimator from kernel
density estimators,
- the N-W estimator as a linear nonparametric regression
estimator,
- asymptotic analysis of the N-W estimator,
- nonparametric regression with fixed (regular) design,
- definition of projection (or orthogonal series) estimators,
- the trigonometric basis as an example of orthonormal basis,
- Sobolev classes and ellipsoids,
- bias and MSE of the coefficient estimators,
- control of the residuals by the condition that the vector of
coefficients belongs to a Sobolev ellipsoid, decomposition of
the MISE of the projection estimator and optimal choice of the
cut-off point,
- upper bound on the MISE for the projection estimator,
- connection between the Gaussian white noise model and
nonparametric regression.
Lower bounds on the minimax risk:
- minimax risk associated with a statistical model and a semi-metric,
- definition of an optimal rate of convergence,
- a general reduction scheme for proving lower bounds,
- main theorem on lower bounds based on many hypotheses using the Kullback-Leibler divergence,
- example of lower bound on the minimax L2-risk for the Hölder class in nonparametric regression estimation with fixed
design.

Face-to-face lectures

Learning assessment procedures

There is both the possibility of taking a written assessment test in classical form with questions related to topics covered in lectures and the possibility of writing a report on findings from the recent literature on nonparametric statistical inference.

Students with disabilities or specific learning disorders (SLD), who intend to request the adaptation of the exam, must follow the instructions given HERE

Assessment

In evaluating the report and the final discussion, the capacity for analysis, methodological rigor and autonomy demonstrated by the Ph.D. candidate will be taken in account.

Criteria for the composition of the final grade

The final grade results from the report grade and a brief discussion/review of the report.

PhD school courses/classes - 2023/2024

Please note: Additional information will be added during the year. Currently missing information is labelled as “TBD” (i.e. To Be Determined).

1. PhD students must obtain a specified number of CFUs each year by attending teaching activities offered by the PhD School.
First and second year students must obtain 8 CFUs. Teaching activities ex DM 226/2021 provide 5 CFUs; free choice activities provide 3 CFUs.
Third year students must obtain 4 CFUs. Teaching activities ex DM 226/2021 provide 2 CFUs; free choice activities provide 2 CFUs.
More information regarding CFUs is found in the Handbook for PhD Students: https://www.univr.it/phd-vademecum

2. Registering for the courses is not required unless explicitly indicated; please consult the course information to verify whether registration is required or not. When registration is actually required, no confirmation e-mail will be sent after signing up. Please do not enquiry: if you entered the requested information, then registration was silently successful.

3. When Zoom links are not explicitly indicated, courses are delivered in presence only.

4. All information we have is published here. Please do not enquiry for missing information or Zoom links: as soon as we get new information, we will promptly publish it on this page.
