Variance Change Point Detection Under a Smoothly-Changing Mean Trend with Application to Liver Procurement
平滑变化均值趋势下的方差变点检测及肝脏获取应用
Literature on change point analysis mostly requires a sudden change in the data distribution, either in a few parameters or the distribution as a whole. We are interested in the scenario, where the variance of data may make a significant jump while the mean changes in a smooth fashion. The motivation is a liver procurement experiment monitoring organ surface temperature. Blindly applying the existing methods to the example can yield erroneous change point estimates since the…
