Anomaly detection

Hi,
I use histogram-based outlier score for anomaly detection but it dose not consider the dependencies between features. Which anomaly detection algorithm should i use to consider the dependencies between features? 
Thanks

That is the nature of HBOS.  I am not entirely what you mean by "dependencies" in this instance, but you should consider one of the distance or density-based outlier approaches such as k-nn Global Anomaly Score or Local Outlier Factor (LOF) which are inherently multivariate in nature.  Be sure to normalize your data first though since they are scale-sensitive!
