The DESIRED electron temperature relations in star-forming regions of the local Universe
M. Orte-García, C. Esteban, J. García-Rojas +7
(Abridged) Aims. We present a homogeneous observational study of electron temperature () relations between ionic species: ([N II]), ([O II]), $T_{\…
The DESIRED temperature-metallicity relations in star-forming regions: probing the Galactic radial and azimuthal metallicity distributions
I. Rafael Martínez-Hernández, J. Eduardo Méndez-Delgado, César Esteban +17
We analyse a sample of 225 star-forming regions from the DESIRED-E project, each with simultaneous determinations of the electron temperature from ionized nitrogen and oxygen, $T_{…
Nonparametric Estimation of Functional Dynamic Factor Model
Israel Martínez-Hernández, Jesús Gonzalo, Graciela González-Farías
Data can be assumed to be continuous functions defined on an infinite-dimensional space for many phenomena. However, the infinite-dimensional data might be driven by a small number…
Nonparametric Trend Estimation in Functional Time Series with Application to Annual Mortality Rates
Israel Martínez-Hernández, Marc G. Genton
Here, we address the problem of trend estimation for functional time series. Existing contributions either deal with detecting a functional trend or assuming a simple model. They c…
Functional Time Series Analysis Based on Records
Israel Martínez-Hernández, Marc G. Genton
In many phenomena, data are collected on a large scale and of different frequencies. In this context, functional data analysis (FDA) has become an important statistical methodology…
