Being outdoors in a natural environment is thought to be restorative and relaxing (Kaplan & Kaplan, 1989). For people with dementia, nature and outdoor spaces (‘ingericht groen’) can provide a stimulating environment with exposure to light and sensory experiences (Burns et al. 2002; GuissetMartinez et al., 2013) as well as engagement in pleasant activities (Mac-Donald, 2002). It is reported tha...

Due to the wide availability of functional data from multiple disciplines, studies analysis have become popular in recent literature. However, related development censored survival has been relatively sparse. In this work, we consider problem analyzing time-to-event presence predictors. We develop a conditional generalized Kaplan–Meier (KM) estimator that incorporates predictors using kernel we...

Kaplan–Meier analyses can be used in many disciplines, e.g., agricultural engineering. Agricultural machinery and vehicles regarded as objects that ‘die’ because, like living creatures, they failed, although after repair until scrapped. This article presents an example of using the estimator to plot reliability function curves five different models Zetor farm tractors. The research shows median...

Background: The difference in restricted mean survival time (rmstD t ð Þ), the area between two survival curves up to time horizon t , is often used in cost-effectiveness analyses to estimate the treatment effect in randomized controlled trials. A challenge in individual patient data (IPD) meta-analyses is to account for the trial effect. We aimed at comparing different methods to estimate the ...
