Because race and neighborhood characteristics are strongly correlated, studies of racial housing price differentials have yielded results that vary widely depending on the types of neighborhood controls used. This paper shows that even with relatively thorough neighborhood controls, there is still evidence that correlation between the error term and regressors is a source of bias. While recent ...

We present a catalogue of OB associations in IC 1613. Using an automatic and objective method (Battinelli’s 1991 technique) 60 objects were found. The size distribution reveals a significant peak at about 60 parsecs if a distance modulus of 24.27 mag is assumed. Spatial distributions of the detected associations and H II regions are strongly correlated.

High-utility itemset mining is the task of finding the sets of items that yield a high utility (e.g. profit) in quantitative transaction databases. An important limitation of previous work on high-utility itemset mining is that utility is generally used as the sole criterion for assessing the interestingness of patterns. This leads to finding many itemsets that have a high profit but contain it...
