Inference for Unit Roots in a Panel Smooth Transition Autoregressive Model where the Time Dimension is Fixed [PDF]
In this paper we derive a unit root test against a Panel Logistic Smooth Transition Autoregressive (PLSTAR). The analysis is concentrated on the case where the time dimension is fixed and the cross section dimension tends to infinity.

Journal of Applied Clinical Medical Physics, Volume 26, Issue 4, April 2025.Abstract Background Inverse planning typically utilizes fast, less accurate dose calculation algorithms during the iterative optimization process, thus leading to dose calculation errors (DCEs) and suboptimal plans that often require dose normalization and/or plan re‐optimization.

Type I and Type II Errors in the Unit Root Determination of a Fractional Brownian Motion [PDF]
Economists who deal with time-series data usually take the unit root test as the ‘prerequisite’ test for a Brownian motion. It is typical for any researchers to apply a battery of well-known unit root tests to their models to confirm stationarity in the ...

Determining the Stationarity Properties of Individual Series in Panel Datasets [PDF]
An attractive feature of panel unit root tests is the ability to exploit coefficient homogeneity under the null hypothesis of a unit root for all series in order to obtain a more powerful test of the unit root hypothesis.

Evaluation of OPTOS wide‐field fundus image projections for radiotherapy planning of uveal melanoma
Journal of Applied Clinical Medical Physics, Volume 26, Issue 4, April 2025.Abstract Purpose To investigate the relationship between the stereographic and azimuthal equidistant projection (AEP) of the human retina for radiotherapy planning with OPTOS optomap wide‐field fundus images (Optos, UK). Further, the geometric accuracy of an OPTOS fundus image is quantified.
