Abstract
We report a measurement of R(b) = GAMMA(bbBAR)GAMMA(had) from Z --> qq BAR events at LEP. Z --> bbBAR events are identified using a multidime nsional analysis based on a neural network approach. We obtain 60% sam ple purity with an efficiency of 35%. Our measured value of R(b) is 0. 222 +/- 0.003 +/- 0.007.
