WebDescription. Fisher Score (Fisher 1936) is a supervised linear feature extraction method. For each feature/variable, it computes Fisher score, a ratio of between-class variance to within-class variance. The algorithm selects variables with largest Fisher scores and returns an indicator projection matrix. Web在合理的情况下,算法是否应该切换到Newton-Raphson更新步骤?默认值为FALSE。 final.re : 合乎逻辑。是否应进行最终Fisher评分重新评估?默认值为FALSE。 control : 估计算法的控制值列表,用于替换函数glmmLassoControl返回的默认值。默认为空列表。
