Linking the Weibull distribution to Gini coefficients: a bamboo specific framework for intra-culm leaf area inequality

open access: yesFrontiers in Plant Science
Quantifying inequality in the leaf area distribution within a single module is critical for elucidating plant resource allocation strategies, but the accuracy of theoretical Gini coefficients derived from statistical distributions remains poorly ...

Sequential Probabilistic Ratio Test for the Scale Parameter of the P-Norm Distribution

open access: yesDiscrete Dynamics in Nature and Society, 2021
We consider a series of independent observations from a P-norm distribution with the position parameter μ and the scale parameter σ. We test the simple hypothesis H0:σ=σ1 versus H1: σ=σ2.

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Parameter Redundancy with Applications in Statistical Ecology [PDF]

open access: yes, 2014
This thesis is concerned with parameter redundancy in statistical ecology models. If it is not possible to estimate all the parameters, a model is termed parameter redundant.

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

open access: yesMolecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Unbiased Estimation of Location and Scale Parameters

open access: yesThe Annals of Mathematical Statistics, 1966
It is well-known that there is a close connection between linear functionals on an appropriate Banach space and unbiased estimators. In Section 2 we prove some results concerning unbiased estimation of location and scale parameters. As application of these results we consider the case of Cauchy density with unknown location [scale] but known scale ...

Post-manoeuvre and online parameter estimation for manned and unmanned aircraft [PDF]

open access: yes, 2013
Parameterised analytical models that describe the trimmed inflight behaviour of classical aircraft have been studied and are widely accepted by the flight dynamics community.

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

open access: yesMolecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

Investigation of scale parameter for the Weibull-Chen distribution

open access: yesResearch in Statistics
Within this article, we estimate the scale parameter for the Weibull-Chen distribution and calculate posterior distributions. This analysis involves the application of the Bayesian technique, which utilizes two non-informative priors along with three ...

Scale parameter distribution.

open access: yes, 2015
Histogram of 22 estimated values for the transmission scale parameter ρ0. The dashed line is a Weibull frequency distribution with mean and variance equal to the mean and variance of the ρ0 estimates for Se = 0.75.
