Open AccessMonitoring invasive alien plants dynamics: application in restored areas
In environmental restoration, evaluating the effect of control actions on alien species is essential for a correct assessment of the success of the restoration. A simple method for the evaluation of the dynami...

On Clustering of Star-Shaped Sets with a Fuzzy Approach: An Application to the Clasts in the Cantabrian Coast
Star-shaped sets represent a large class of sets that contains compact and convex ones as a particular case. The center-radial characterization of these sets is very useful to identify their original shape. Th...

Applying Statistical Methods with Imprecise Data to Quality Control in Cheese Manufacturing
Sensory analysis entails subjective valuations provided by qualified experts which in most of the cases are given by means of a real value. However personal valuations usually present an uncertainty in their m...

The Spiking Problem in the Context of the Isotonic Regression
The usual estimators of the regression under isotonicity are known to present the so-called spiking problem, that is, they are very sensitive at the tails. Three design-based strategies in order to alleviate this...

On Some Concepts Related to Star-Shaped Sets
The convenient theoretical properties of the support function and the Minkowski addition-based arithmetic have been shown to be useful when dealing with compact and convex sets on

Bootstrap Comparison of Statistics for Testing the Homoscedasticity of Random Fuzzy Sets
The problem of testing the equality of variances of k random fuzzy sets has been recently developed on the basis of Levene’s classical procedure. Asymptotic and bootstrap approaches have been carried out in this ...

Bootstrap Confidence Intervals for the Parameters of a Linear Regression Model with Fuzzy Random Variables
Confidence intervals for the parameters of a linear regression model with a fuzzy response variable and a set of real and/or fuzzy explanatory variables are investigated. The family of LR fuzzy random variables i...

An Alternative Approach to the Median of a Random Interval Using an L 2 Metric
Since the Aumann-type expected value of a random interval is not robust, the aim of this paper is to propose a new central tendency measure for interval-valued data. The median of a random interval has already...

Linear Regression Analysis for Interval-valued Data Based on Set Arithmetic: A Review
When working with real-valued data regression analysis allows to model and forecast the values of a random variable in terms of the values of either another one or several other random variables defined on the...

Chapter
Testing the Variability of Interval Data: An Application to Tidal Fluctuation
A methodology for analyzing the variability of the tidal fluctuation in a specific area is proposed in this work. The idea is to consider intervals determined by the minimum and maximum height reached by the t...

Chapter
Arithmetic and Distance-Based Approach to the Statistical Analysis of Imprecisely Valued Data
Most of the research developed in the last years by the SMIRE Research Group concerns the statistical analysis of imprecisely (set- and fuzzy set)-valued experimental data. This analysis has been based on an a...

Integrating statistical information concerning historical floods: ranking and interval return period estimation
The importance of the historical information in flood analysis has previously been underlined. In this context, we present an integral methodology aimed at the establishment of return periods of different floo...

Fuzzy vs. Likert Scale in Statistics
Likert scales or associated codings are often used in connection with opinions/valuations/ratings, and especially with questionnaires with a pre-specified response format.A guideline to design questionnaires a...

A comparison of point-scoring procedures for species prioritization and allocation of seed collection resources in a mountain region
Setting species priorities is commonly based on the assessment of multiple conservation criteria, and point-scoring methods are broadly used for obtaining ranked species lists. However, the implications of dif...

Valuation of Environmental Resources: The Case of the Brown Bear in the North of Spain
This work concerns the contingent valuation of endangered species. Specifically, it is devoted to quantify and model the value of the brown bear and its habitat in a society in the north of Spain. A single-bou...

Modelling shallow landslide susceptibility: a new approach in logistic regression by using favourability assessment
A new method for estimating shallow landslide susceptibility by combining Geographical Information System (GIS), nonparametric kernel density estimation and logistic regression is described. Specifically, a lo...

One-sample tests for a generalized Fréchet variance of a fuzzy random variable
A procedure to test hypotheses about the population variance of a fuzzy random variable is analyzed. The procedure is based on the theory of UH-statistics. The variance is defined in terms of a general metric ...
