^{a}%: the percentage of nonzero β’s overlapped with each other in two datasets

^{b}
ρ: correlation coefficients between two neighbor variables in each cluster

^{c}
α: the estimated value of α which control the weight of two ranks in geometric mean

^{d}SIS: variables were sorted by marginal correlation using only internal dataset

^{e}iSIS: iterative version of SIS

^{f}SKI: variables were sorted by weighted geometric mean of two marginal correlation based ranks using two dataset

^{g}iSKI: iterative version of SKI
