Local likehood regression estimation for circular covariates

M. Alonso-Pena, I. Gijbels, R. M. Crujeiras

Circular data are periodic observations that can be regarded as points on a unit circumference. These types of data are found in a many different fields such as psuchology, meteorology or biology, and can be found jointly with other real-valued variables. We propose a general approach that allows to estimate, nonparametrically, regression functions with a circular predictor and a general response, which can be either a continuous or a discrete variable. The estimation consists of hte maximization of a circular kernel weighted log-likelihood. The obtainment of the bias and variance of the estimators is also addressed, as well as the problemn of the selection of the smoothing parameter. The proposal will be illustrated with some real data applications.

Keywords: circular data, data-driven smoothing selection, kernel regression, local likelihood

    Visit Alhambra

    Tomorrow, Thursday, we will visit the Alhambra. 1. At 7:00 p.m., buses will start leaving from the door of the Hotel Granada Center (in front of the door of the Faculty of Sciences) 2. Upon arrival, groups with guides will be organized. 3. There will be groups in English language. These groups will wait at the destination until the arrival of all buses. 4. After the visit to the Alhambra we will walk to the Carmen de los Mártires to have a cocktail. 5. On the way back, we can go back by bus, which will leave from the same place where they left us at the Alhambra. 6. Although the way to the Alhambra by bus seems long, it really is close to the city. We invite you, whoever wishes, to go down for a pleasant walk. 7. Do not forget to take your Alhambra ticket and your identity card or passport.
