What does information value mean?
Information has Value acknowledges that the creation of information and products derived from information requires a commitment of time, original thought, and resources that need to be respected by those seeking to use these products, or create their own based on the work of others.
What does negative weight of evidence mean?
Negative weight of evidence (WoE) means that given characteristic shouldn’t be used as a predictor in credit scoring model.
What is weight of evidence and information value?
The weight of evidence (WOE) and information value (IV) provide a great framework for for exploratory analysis and variable screening for binary classifiers. WOE and IV have been used extensively in the credit risk world for several decades, and the underlying theory dates back to the 1950s.
What are the advantages and disadvantages of logistic regression?
Let’s discuss some advantages and disadvantages of Linear Regression. Logistic regression is easier to implement, interpret, and very efficient to train. If the number of observations is lesser than the number of features, Logistic Regression should not be used, otherwise, it may lead to overfitting.
Can information value be greater than 1?
Yes, it does have an upper bound, but not 1. The mutual information (in bits) is 1 when two parties (statistically) share one bit of information. However, they can share a arbitrary large data.
What is the weight of evidence?
Weight of evidence refers to a systematic approach that scientists use to evaluate the totality of scientific evidence to assess if the science supports a particular conclusion.
Why media and information literacy is important?
Because being media literate means being able to access, analyze, and evaluate information, which we receive through media. Being media literate means being able to create media messages and to use the technology tools available to us. It means being able to think critically and speak confidently.
What is IV in machine learning?
Weight of evidence (WOE) and Information value (IV) are simple, yet powerful techniques to perform variable transformation and selection. These concepts have huge connection with the logistic regression modeling technique. It is widely used in credit scoring to measure the separation of good vs bad customers.
How is the value of information determined?
The value of information is determined by its importance to the decision maker or to the outcome of the decision being made.
What is a good information value?
Rules related to Information Value 0.1 to 0.3, then the predictor has a medium strength relationship to the Goods/Bads odds ratio. 0.3 to 0.5, then the predictor has a strong relationship to the Goods/Bads odds ratio. > 0.5, suspicious relationship (Check once)
How is logistic regression used in industries?
Unlike linear regression models, which are used to predict a continuous outcome variable, logistic regression models are mostly used to predict a dichotomous categorical outcome, LRAs are frequently used in business analysis applications. For example, you can analyze if a customer will purchase a product or not.
Who formulated standards of information literacy for higher education?
In 2000, the Association of College and Research Libraries (ACRL), a division of the American Library Association (ALA), released “Information Literacy Competency Standards for Higher Education”, describing five standards and numerous performance indicators considered best practices for the implementation and …
What are examples of information literacy?
Examples of these include planning, searching (searching for information, searching the web, Boolean searching and keywords) and evaluation (suitability and reliability of information source and currency of information).
What are the applications of logistic regression?
Applications. Logistic regression is used in various fields, including machine learning, most medical fields, and social sciences. For example, the Trauma and Injury Severity Score (TRISS), which is widely used to predict mortality in injured patients, was originally developed by Boyd et al. using logistic regression.
Why should WoE be monotonic?
The WoE transformation through monotonic binning provides a convenient way to address each of aforementioned concerns. It is also worth mentioning that a numeric variable and its strictly monotone functions should converge to the same monotonic WoE transformation.
What are the elements of information literacy?
The term “information literacy” describes a set of abilities that enables an individual to acquire, evaluate, and use information. You can think of information literacy as having five components: identify, find, evaluate, apply, and acknowledge sources of information.
What are the four core competencies of digital literacy?
Globally, the International Society for Technology in Education (ISTE) frames its benchmarks for digital literacy around six standards: creativity and innovation; communication and collaboration; research and information fluency; critical thinking, problem solving and decision making; digital citizenship; and …
