Detecting Location Shifts during Model Selection by Step-Indicator Saturation [PDF]
Econometrics, 2015 To capture location shifts in the context of model selection, we propose selecting significant step indicators from a saturating set added to the union of all of the candidate variables.

Along- and Cross-Track Relocation for Ground Moving Target in a Squint Multichannel SAR System. [PDF]
Sensors (Basel)The squint synthetic aperture radar (SAR) offers flexible beam pointing control and a wider range of applications compared to the side-looking SAR. Unlike the latter, ground moving targets exhibit shifts in both along-track and cross-track directions in ...

Wavelet-Tsallis Entropy Detection and Location of Mean Level-Shifts in Long-Memory fGn Signals
Entropy, 2015 Long-memory processes, in particular fractional Gaussian noise processes, have been applied as models for many phenomena occurring in nature. Non-stationarities, such as trends, mean level-shifts, etc., impact the accuracy of long-memory parameter ...

Gaze Tracking of Pitched Balls in Coupled and Uncoupled Tasks. [PDF]
Vision (Basel)Studies suggest that anticipation in sports-related tasks is better if the task maintains the coupling of perception and action required in competition. Study 1 addressed the question of whether gaze tracking varies between coupled tasks in baseball and ...

Selecting a Model for Forecasting
Econometrics, 2021 We investigate forecasting in models that condition on variables for which future values are unknown. We consider the role of the significance level because it guides the binary decisions whether to include or exclude variables.
