An Active Approach to Characterizing Dynamic Dependencies
... • Dependency models help problem determination • ADD effectively discovers dependency models – approach is uniquely positioned in the design space » active, indirect approach finds dynamic, distributed dependencies; works on black-box systems ...

multilevel analysis - the Department of Statistics
... Arguments for choosing between fixed (F ) and random (R) coefficient models for the group dummies: 1. If groups are unique entities and inference should focus on these groups: F . This often is the case with a small number of groups. 2. If groups are regarded as sample from a (perhaps hypothetical) ...

Towards a Numerical Rule Mining Language
... proposed language with function terms. The work of [14] studies the problem of mining optimized rules of the form A ∈ [a, b] ∧ C1 ⇒ C2 on a database table. Here, A is a column name and C1 , C2 are equality constraints on columns, as in year ∈ [1990, 2000] ∧ src city = N Y ⇒ dest city = P aris. In ou ...
