Frank Dance's helical model of communication was initially published in his 1967 book Human Communication Theory. [161] [162] [163] It is intended as a response to and an improvement over linear and circular models by stressing the dynamic nature of communication and how it changes the participants. Dance sees the fault of linear models as ...
An econometric model then is a set of joint probability distributions to which the true joint probability distribution of the variables under study is supposed to belong. In the case in which the elements of this set can be indexed by a finite number of real-valued parameters , the model is called a parametric model ; otherwise it is a ...
An economic model is a theoretical construct representing economic processes by a set of variables and a set of logical and/or quantitative relationships between them. The economic model is a simplified, often mathematical, framework designed to illustrate complex processes.
Econometrics may use standard statistical models to study economic questions, but most often they are with observational data, rather than in controlled experiments. [10] In this, the design of observational studies in econometrics is similar to the design of studies in other observational disciplines, such as astronomy, epidemiology, sociology and political science.

Econometric models are used by economists to estimate relationships between large numbers of variables, most importantly to model national economies or the world economy. Econometric models is included in the JEL classification codes as JEL: C5

[4] [5] Later, Wilbur Schramm introduced a model that identified multiple variables in communication which includes the transmitter, encoding, media, decoding, and receiver. [ 6 ] In Berlo's SMCR model, the sender is one who sends the message, the receiver receives the message, which is transmitted through the channel where disturbances might ...
