Robust tests for linear regression models based on τ-estimates
(Elsevier Science, 2016-01)
ANOVA tests are the standard tests to compare nested linear models fitted by least squares. These tests are equivalent to likelihood ratio tests, so they have high power. However, least squares estimators are very vulnerable ...
A country bug in the city: Urban infestation by the Chagas disease vector Triatoma infestans in Arequipa, Peru
(BioMed Central, 2013)
Background: Interruption of vector-borne transmission of Trypanosoma cruzi remains an unrealized Objetive: in many Latin American countries. The task of vector control is complicated by the emergence of vector insects in ...
Robust Wald type methods for testing equality between two populations regression parameters: A comparative study under the logistic model
(Elsevier Science, 2020-08-28)
Comparing the regression parameters between two populations is useful to understand the homogeneity of the process underlying the data. The problem of logistic regression is considered when the practitioner handles data ...
Regressions of the dielectric constant and speed of sound of vegetable oils from their composition and temperature using genetic programming
(Elsevier, 2021-12)
The dielectric constant (DC) and speed of sound (SoS) have been measured in many studies on vegetable oils (VOs). These measurements can be applied for quality control, for the detection of contaminants, and in works related ...
Robust accelerated failure time regression
(Elsevier Science, 2011-01)
Robust estimators for accelerated failure time models with asymmetric (or symmetric) error distribution and censored observations are proposed. It is assumed that the error model belongs to a log-location-scale family of ...
Sucient dimension reduction and prediction in regression: Asymptotic results
(Elsevier Inc, 2019-03)
We consider model-based sufficient dimension reduction for generalized linear models and prove the consistency and asymptotic normality of the prediction estimator studied empirically for the normal case by Adragni and ...
