Modeling pseudo-observations with covariate dependent censoring: robustness of the method against misspecified censoring models [PDF]
, 2018 The so called pseudo-observations in survival analysis were introduced by recent studies that reviewed this method when estimating different parameters using regressions models (Andersen and Perme, Stat. Meth. Med. Res., 2010) with the condition that the

Annals of Gastroenterological Surgery, EarlyView.Although neoadjuvant chemotherapy with fluorouracil, cisplatin, and docetaxel (NAC‐DCF) is the current standard neoadjuvant regimen for esophageal squamous cell carcinoma, its substantial toxicity underscores the need to identify patients who derive the greatest benefit.

Exponential life test plans under progressive type-I interval censoring
, 2010 碩士傳統的壽命檢驗計畫，通常採用型一或型二設限方法來蒐集資料，但傳統的設限方法不允許在實驗中移除存活的實驗單位，且必須連續地監控產品，當我們因故或基於實驗上的方便無法連續檢驗產品，且在實驗中對存活的產品做移除時，就必須採用逐步區間設限方法進行實驗，本論文結合型一設限、區間設限及逐步設限方法，探討當產品壽命服從指數分配時，如何建立壽命檢驗計畫，在給定生產者風險與消費者風險下，求出壽命檢驗計畫所需的最小樣本數，以及檢定壽命的臨界值，並將以上結果編製成表，以利實務界使用。Traditional life ...

Annals of Gastroenterological Surgery, EarlyView.This study evaluated immune‐related biomarkers in esophageal squamous cell carcinoma treated with immune checkpoint inhibitors after postoperative recurrence. PD‐L1 expression in tumor‐associated macrophages and tumor cells, together with HLA class I downregulation and HLA‐DR expression, were associated with favorable responses to immunotherapy.

Annals of Gastroenterological Surgery, EarlyView.This study aimed to determine whether immuno‐nutritional and inflammatory markers could serve as predictors of the outcomes of postoperative adjuvant chemotherapy for stage III colorectal cancer in elderly patients. Postoperative lymphocyte‐to‐monocyte ratio and postoperative C‐reactive protein‐to‐albumin ratio accurately predicted the efficacy of ...

Censored Quantile Regression Redux
Quantile regression for censored survival (duration) data offers a more flexible alternative to the Cox proportional hazard model for some applications. We describe three estimation methods for such applications that have been recently incorporated into ...

Estimating panel data duration models with censored data [PDF]
This paper presents a method for estimating a class of panel data duration models, under which an unknown transformation of the duration variable is linearly related to the observed explanatory variables and the unobserved heterogeneity (or frailty) with

Human‐in‐the‐Loop Swarms: A Bionic Swarm Approach to Real‐World Soil Mapping
Advanced Intelligent Systems, EarlyView.This article introduces the “Bionic Swarm,” a novel system that lowers the barriers to real‐world swarm validation by abstracting difficult hardware tasks to app‐guided human agents. We demonstrate the system's utility through the experimental validation of a geotechnical soil‐mapping swarm algorithm and show superior performance to baseline approaches

The role of venture‐financed startups in innovation for US agriculture
American Journal of Agricultural Economics, EarlyView.Abstract To evaluate the role played by startup companies in the innovation ecosystem of US agriculture, we compile a unique dataset of 6024 new entrants founded 1987–2019 that details their financing lifecycles, annual economic performance, and patenting activities.
