Although they were considering an agricultural context, the problem is closely analogous to that of conducting a meta-analysis of clinical trials, which in turn has close similarities to the business of analysing multi-centre trials[2]. In fact, it has been suggested that meta-analysis ought to be employed on...

BACKGROUND We aimed to assess the high-risk group for suicide using different classification methods includinglogistic regression (LR), decision tree (DT), artificial neural network (ANN), and support vector machine (SVM).

Our aim is to confirm the nature of the long period radial velocity measurements for β Gem first found by Hatzes & Cochran (1993). We present precise stellar radial velocity measurements for the K giant star β Gem spanning over 25 years. An examination of the Ca II K emission, spectral line shapes from high resolution data (R = 210,000), and Hipparcos photometry was also made to discern the tru...
