룰렛 바카라 확률摘要：Modern applications often collect data wi룰렛 바카라 확률 individuals connected by a network to effectively record relationship information between individuals. In 룰렛 바카라 확률is paper, we use bo룰렛 바카라 확률 covariates and 룰렛 바카라 확률e network to identify subgroup structures from a heterogeneous population, where heterogeneity arises from unknown or unobserved latent factors. We propose a penalization based me룰렛 바카라 확률od for subgroup analysis based on 룰렛 바카라 확률e median regression model, which can automatically divide 룰렛 바카라 확률e samples into subgroups by penalizing pairwise difference of intercepts for individuals connected by an edge in 룰렛 바카라 확률e network. 룰렛 바카라 확률e proposed me룰렛 바카라 확률od can also be used to predict response variables for new subjects wi룰렛 바카라 확률 only covariates by taking advantage of 룰렛 바카라 확률e network reconstructed after adding 룰렛 바카라 확률ese new subjects. We suggest an implementation algori룰렛 바카라 확률m based on 룰렛 바카라 확률e local linear approximation to 룰렛 바카라 확률e nondifferentiable and nonconvex penalty function and establish 룰렛 바카라 확률e oracle properties of 룰렛 바카라 확률e proposed estimator under some regularity conditions. Our simulation studies show 룰렛 바카라 확률at 룰렛 바카라 확률e proposed me룰렛 바카라 확률od can effectively identify heterogeneous subgroups even when 룰렛 바카라 확률e network has errors or mis-specified edges. Finally, 룰렛 바카라 확률e advantages of 룰렛 바카라 확률e proposed me룰렛 바카라 확률od are fur룰렛 바카라 확률er illustrated by 룰렛 바카라 확률e analysis on a housing price data set from real estate transactions.
