  This article introduces CluBear, a Python-based open-source package for
interactive massive data analysis. The key feature of CluBear is that it
enables users to conduct convenient and interactive statistical analysis of
massive data with only a traditional single-computer system. Thus, CluBear
provides a cost-effective solution when mining large-scale datasets. In
addition, the CluBear package integrates many commonly used statistical and
graphical tools, which are useful for most commonly encountered data analysis
tasks.
