but e.g. in classification, naive Bayes converges quicker but has typically a higher error than logistic regression. On small datasets you’d might want to try out naive Bayes, but as your training set size grows, you likely get better results with logistic regression....
A common method of reporting the result of logistic regression is to provide an odds ratio and its corresponding confidence interval. The results of such statistical analyses cannot be further evaluated with respect to the consistency of confidence intervals between the odds ratio and the difference ...

这是因为Naive bayes是生成模型,假设训练数据服从某种分布,在有prior的情况下模型能够把数据fit的更好,但是随着数据量的增多,prior对整个数据后验概率分布的影响逐渐降低。而Logistic regression属于判别模型,不去建模联合概率,通过训练数据直接预测输出,因此在数据足够多的情况下能够得到更好一些的效果。
An algorithm that is capable of learning a regression predictive model is called a regression algorithm. Some algorithms have the word “regression” in their name, such as linear regression and logistic regression, which can make things confusing because linear regression is a regression algorithm wh...
Proof that the estimated odds ratio is constant in logistic regression Let there be a binary outcomey; we will sayy=0 ory=1, and let us assume that Pr(y==1) = F(Xb) whereXandbare vectors and F() is some cumulative distribution. ...
The multiple logistic regression analysis revealed that obesity, female gender, creatinine clearance (CCr), and a ratio of transmitral E velocity to early diastolic mitral annular velocity (E/ E')>15 were independently associated with the prevalence of heart failure with preserved EF. Patients with...

Multivariate regression and logistic regression analysis was used to determine predictors of goal differences, and match outcome. Winning teams perform fewer positional attacks (d=0.51) and more fast breaks (η2=0.01). Winning teams score significant higher number of goals in attack (d=1.43), ...
Subsequently, for node classification, we employ these representations to train and test an L2-regularized logistic regression (LR) classifier. For node clustering, we evaluate the proposed method under the clustering evaluation protocol and cluster the learned representations using the K-Means algorithm...
