EFA can refer to different things depending on the context. Here are some possible meanings:
-
Exploratory Factor Analysis: In multivariate statistics, exploratory factor analysis (EFA) is a statistical method used to uncover the underlying structure of a relatively large set of variables. EFA is a technique within factor analysis whose overarching goal is to identify the common factors and the related manifest variables.
-
Equipment Finance Agreement: An equipment finance agreement (EFA) is a type of financing that is like a loan, security agreement, and promissory note all packaged together into a single document. EFAs have some distinct advantages compared to bank loans, such as speed, flexibility, and convenience, and they often dont require additional collateral beyond the financed equipment itself.
-
Essential Fatty Acids: Essential fatty acids (EFAs) are fatty acids that the body needs but cannot synthesize, so they must be ingested. There are two types of EFAs: omega−3 (n−3) and omega−6 (n−6). EFAs serve important metabolic roles in providing the necessary building blocks for the bodys normal growth, repair, and function. They are used to create prostaglandins, which are hormone-like chemical messengers responsible for regulating blood pressure, oxygen transport, pain, and inflammation. EFAs also maintain the liquid barrier surrounding each cell and transport waste and nutrients in and out of cells. Given their role in cell activity, EFAs may have an influence on brain function as well as the cardiovascular, inflammatory, and immune systems.
-
Elastic Fabric Adapter: Elastic Fabric Adapter (EFA) is a network interface for Amazon EC2 instances that enables customers to run applications requiring high levels of inter-node communications at scale on AWS. Its custom-built operating system (OS) bypass hardware interface provides a low-latency, low-jitter channel for inter-instance communications, making tightly-coupled HPC or distributed machine learning applications run faster. EFA is available as an optional EC2 networking feature that you can enable on any supported EC2 instance at no additional cost.
In summary, EFA can refer to exploratory factor analysis, equipment finance agreements, essential fatty acids, or elastic fabric adapters, depending on the context.
