Common structure in panels of short time series

Yao, Qiwei; Tong, Howell; Finkenstädt, Bärbel; … - London School of Economics (LSE) - 2000

Typically, in many studies in ecology, epidemiology, biomedicine and others, we are confronted with panels of short time–series of which we are interested in obtaining a biologically meaningful grouping. Here, we propose a bootstrap approach to test whether the regression functions or the...
