Two statistical problems for multivariate mixture distributions
Ricardo Fraiman, Leonardo Moreno, Thomas Ransford
We address two important statistical problems: that of estimating mixtures of multivariate normal distributions and mixtures of -distributions based on univariate projections, a…
Statistical analysis of measures of non-convexity
Alejandro Cholaquidis, Ricardo Fraiman, Leonardo Moreno +1
Several measures of non-convexity (departures from convexity) have been introduced in the literature, both for sets and functions. Some of them are of geometric nature, while other…
Universally consistent estimation of the reach
Alejandro Cholaquidis, Ricardo Fraiman, Leonardo Moreno
The reach of a set , also known as condition number when is a manifold, was introduced by Federer in 1959. The reach is a central concept in geometric me…
Application of the Cramér-Wold theorem to testing for invariance under group actions
Ricardo Fraiman, Leonardo Moreno, Thomas Ransford
We address the problem of testing for the invariance of a probability measure under the action of a group of linear transformations. We propose a procedure based on consideration o…
Home range estimation under a restricted sampling scheme
Alejandro Cholaquidis, Ricardo Fraiman, Manuel Hernandez-Banadik
The analysis of animal movement has gained attention recently. New continuous-time models and statistical methods have been developed to estimate some sets related to their movemen…
Weighted lens depth: Some applications to supervised classification
Alejandro Cholaquidis, Ricardo Fraiman, Fabrice Gamboa +1
Starting with Tukey's pioneering work in the 1970's, the notion of depth in statistics has been widely extended especially in the last decade. These extensions include high dimensi…
