Denis McQuail was born in Wallington, London on 12 April 1935 to Irish immigrant parents Annie (née Mullan) and Christopher McQuail. [4] After schooling at St Anselm's college in Birkenhead, where he showed an aptitude for languages, he spent his national service in the Intelligence Corps learning Russian and studied history at Corpus Christi College, Oxford.

In 1969 Jay Blumler and Denis McQuail studied the 1964 election in the United Kingdom by examining people's motives for watching certain political programs on television. By categorizing the audience's motives for viewing a certain program, they aimed to understand any potential mass-media effects by classifying viewers according to their needs. [7]
In 1993, the communication scholars Denis McQuail and Sven Windahl referred to Lasswell's model as "perhaps the most famous single phrase in communication research." [18] McQuail and Windahl also considered the model as a formula that would be transformed into a model once boxes were drawn around each element and arrows connected the elements. [18]
Identifiability of the model in the sense of invertibility of the map is equivalent to being able to learn the model's true parameter if the model can be observed indefinitely long. Indeed, if {X t} ⊆ S is the sequence of observations from the model, then by the strong law of large numbers,
The first known prominent public usage of the term "Model-Based Systems Engineering" is a book by A. Wayne Wymore with the same name. [8] The MBSE term was also commonly used among the SysML Partners consortium during the formative years of their Systems Modeling Language (SysML) open source specification project during 2003-2005, so they could distinguish SysML from its parent language UML v2 ...

Model fit measures could then be obtained to assess how well the proposed model captured the covariance between all the items or measures in the model. If the constraints the researcher has imposed on the model are inconsistent with the sample data, then the results of statistical tests of model fit will indicate a poor fit, and the model will ...
Judea Pearl defines a causal model as an ordered triple ,, , where U is a set of exogenous variables whose values are determined by factors outside the model; V is a set of endogenous variables whose values are determined by factors within the model; and E is a set of structural equations that express the value of each endogenous variable as a function of the values of the other variables in U ...
