Most marketplaces, in order to function properly, require some form of identification of their users.It is a well-known problem that the ability of participants to generate easily new identities can lead to many problems.
Springer, Cham In medical studies, the receiver operating characteristic (ROC) curve is a tool of extensive use to analyze the discrimination capability of a diagnostic variable.
We provide theoretical arguments for the validity of the estimator and demonstrate its application to data.
For obvious reasons, I will not reveal the names of the victims :-) Perhaps in the future we will see the emergence of identification services for individuals.
We already have such services for websites (e.g., Verisign).
Classification accuracy is the ability of a marker or diagnostic test to discriminate between two groups of individuals, cases and controls, and is com- monly summarized by using the receiver operating characteristic (ROC) curve.
We describe three ways of using covariate information.
ABSTRACT: Although alpha-fetoprotein (AFP) is the most widely used biomarker in hepatocellular carcinoma (HCC) surveillance, disease activity may also increase AFP levels in chronic hepatitis B (CHB).
Since nucleos(t)ide analog (NA) therapy may reduce not only HBV viral loads and transaminase levels but also the falsely elevated AFP levels in CHB, we tried to determine whether exposure to NA therapy influences AFP performance and whether selective application can optimize the performance of AFP testing in CHB during HCC surveillance.
A form of identification that is considered strong is to ask for unique ID element from the registering users, e.g., the SSN of the participant, asking for place of birth, etc. Souma Miura: Interestingly enough, I was able to fool quite a few websites that supposedly guarantee for the identity of their participants.
Interestingly enough, it is trivially easy to bypass many such identity tests. You can specify the characteristics of the name that you want, and you get back an entry that you want. All of them accepted without problems the fake identities, and in some cases even the credit card numbers (not for actual charges but the fake credit card numbers were accepted as legitimate credit cards to create a profile).
Rather than creating main choices in our private country, we are compelled to change our arrangements to incorporate the yearnings of other individuals.
