Latent variable - Latent variables, as opposed to observable variables, are those variables that cannot be directly observed but are rather inferred from other variables that can be observed and directly measured. Examples of latent variables include quality of life, business confidence, morale, happiness, conservatism.
Observable variable - Observable variables, as opposed to latent variables, are those variables that can be observed and directly measured.
Free variables and bound variables - In mathematics, and in other disciplines involving formal languages, including mathematical logic and computer science, a free variable is a notation for a place or places in an expression, into which some definite substitution may take place, or with respect to which some operation (summation or quantification, to give two examples) may take place. The idea is related to, but somewhat deeper and more complex than, that of a placeholder (a ...
Expectation-maximization algorithm - In statistical computing, an expectation-maximization (EM) algorithm is an algorithm for finding maximum likelihood estimates of parameters in probabilistic models, where the model depends on unobserved latent variables. EM is frequently used for data clustering in machine learning and computer vision.
