Symmetrically Trimmed Least Squares Estimation for Tobit Models [PDF]

Econometrica, 1986
This paper proposes alternatives to maximum likelihood estimation of the censored and truncated regression models (known to economists as ``Tobit'' models). The proposed estimators are based upon symmetric censoring or truncation of the upper tail of the distribution of the dependent variable.

Enhanced Dynamic Performance in Hybrid Power System Using a Designed ALTS-PFPNN Controller

Energies, 2022
The large-scale, nonlinear and uncertain factors of hybrid power systems (HPS) have always been difficult problems in dynamic stability control. This research mainly focuses on the dynamic and transient stability performance of large HPS under various ...

RobPer: An R Package to Calculate Periodograms for Light Curves Based on Robust Regression

Journal of Statistical Software, 2016
An important task in astroparticle physics is the detection of periodicities in irregularly sampled time series, called light curves. The classic Fourier periodogram cannot deal with irregular sampling and with the measurement accuracies that are ...

Combining some Biased Estimation Methods with Least Trimmed Squares Regression and its Application

Revista Colombiana de Estadística
In the case of multicollinearity and outliers in regression analysis, the researchers are encouraged to deal with two problems simultaneously. Biased methods based on robust estimators are useful for estimating the regression coefficients for such cases.

Profiling neoadjuvant therapy response in rectal cancer using meta‐analysis of publicly available transcriptomic RNA‐seq datasets

Molecular Oncology, EarlyView.
This study integrates publicly available transcriptomic datasets to identify molecular signatures associated with response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer. By analyzing a combination of multiple cohorts with bioinformatics approaches, we reveal biological pathways and immune‐related features that may improve ...

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...
