What is Audit Trail ? An audit trail is a record of all the steps taken during a financial transaction or process. This includes any changes made to the transaction, as well as the date and time of each change. The purpose of an audit trail is to provide a clear and detailed record of […]

What is Attribute ? An attribute is a characteristic or quality that describes an object or individual. It provides additional information about the subject and helps to differentiate it from others. For example, the color of a fruit is an attribute that helps to identify it as a red apple or a yellow banana. The […]

What is Asymmetric proximity matrices ? Asymmetric proximity matrices are a type of proximity matrix that are used in data analysis and machine learning. These matrices are used to represent the relationship between different objects or entities, and they are typically used in clustering and classification algorithms. An asymmetric proximity matrix is different from a […]

What is Asymmetric maximum likelihood (AML) ? Asymmetric maximum likelihood (AML) is a statistical method used to estimate model parameters in cases where the likelihood function is not symmetrical. This can occur when there is a significant difference in the variance of the data for different values of the model parameters. One example of when AML […]

What is Asymmetrical Distribution ? Asymmetrical distribution, also known as skewed distribution, is a type of probability distribution where the values are not evenly distributed around the central value or mean. In other words, the distribution is not symmetrical, with the values being concentrated more on one side of the mean than the other. This can […]

What are Assumptions ? An assumption is a statement or belief that is accepted as true without sufficient evidence or proof. It is a supposition or a belief that is taken for granted, without any concrete evidence or confirmation. Assumptions are often made based on previous experiences or knowledge, and they help people make sense […]

What is Association ? Association is a type of relationship that exists between two or more entities. This relationship can be represented using various techniques in data science, such as correlation or the construction of association rules. One common example of association is the relationship between the items that a customer purchases at a grocery store. […]

What are Artificial Neural Networks ? An artificial neural network is a computational model that is inspired by the way biological neurons work in the human brain. It is a machine learning algorithm that is designed to recognize patterns in data and make predictions or take actions based on that data. At the core of […]

What is Artificial Intelligence ? Artificial Intelligence, also known as AI, is the concept of machines being able to exhibit human-like intelligence. This includes the ability to think, learn, and problem-solve. AI is a rapidly growing field that has the potential to revolutionize many aspects of our lives. One common example of AI is in […]

ARMA : ARMA, or Autoregressive Moving Average, is a type of statistical model used in time series analysis to capture the effects of past values on current values in the data. It is a combination of two models: autoregression (AR) and moving average (MA). Autoregression is a type of regression analysis where the dependent variable […]
