Shu-Fei Wu
2022 Mathematics  
Under heteroscedasticity, we propose one-stage multiple comparison procedures for several treatment groups compared with several control groups in terms of exponential mean lifetimes.  ...  The simultaneous confidence intervals including one-sided and two-sided confidence intervals for the difference between the mean lifetime from the i-th treatment group and the mean lifetime from the j-th  ...  Thus, the data analysis one-stage multiple comparison procedures with several controls µ i − µ * j , i = 1, 2, j = 1, 2 in Theorem 1 for exponential mean lifetimes under heteroscedasticity can be applied  ...

Multilevel Emulation for Stochastic Computer Models with Application to Large Offshore Wind farms [article]

Jack C. Kennedy, Daniel A. Henderson, Kevin J. Wilson
2021 arXiv   pre-print
We also conduct a probabilistic sensitivity analysis to understand the influence of key parameters in the wind farm model which will help us to plan a probability elicitation in the future.  ...  We present a novel heteroscedastic Gaussian Process emulator which exploits cheap approximations to a stochastic offshore wind farm simulator.  ...  The main effect plots for the mean are quite similar with the exception of f6 (x6 ).  ...
