thus substantially overcalling deleteriousness. REVEL scores of 0.8–1.0 had a Positive Likelihood Ratio (PLR) of 6.74 (5.24–8.82) compared to scores <0.7 and scores of 0–0.4 had a Negative Likelihood Ratio (NLR) of 34.3 (31.5–37.3) compared to scores of >0.7. For Meta-SNP, the equi...
网络阴性似然比;阴性相似比;阴性概率比 网络释义
混淆矩阵中有着Positive、Negative、True、False的概念,其意义如下:称预测类别为1的为Positive(阳性),预测类别为0的为Negative(阴性)。预测正确的为True(真),预测错误的为False(伪)。对上述概念进行组合,就产生了如下的混淆矩阵:然后,由此引出True Positive
PPV: positive predictive value; NPV: negative predictive value; LR+: positive likelihood ratio = sensitivity/(1--specificity); LR-: negative likelihood ratio = (1--sensitivity)/specificity.

The pooled sensitivity, specificity, positive likelihood ratio (+LR) and negative likelihood ratio (–LR) were calculated to assess the diagnostic value of elastography (Li et al. 2018). Pooled data were presented by 95% CIs and displayed using forest plots (Bossuyt et al. 2013). A summar...
This data must be multiplied by -1 before being passed to the quantizer, because, in soft-decision mode, the Viterbi decoder assumes that positive numbers correspond to 1s and negative numbers to 0s. Pass the quantizer output to the Viterbi decoder. Compute the error statistics. Get ...
