The Form of Structural Equation Models
Structural equation modeling incorporates several different approaches or frameworks to representing these models. In one well-known framework (popularized by Karl Jöreskog, University of Uppsala), the general structural equation model can be represented by three matrix equations:

However, in applied work, structural equation models are most often represented graphically. Here is a graphical example of a structural equation model:

For more information, click on an element of this diagram, or choose from this list: Latent Constructs | Structural Model | Structural Error | Manifest Variables | Measurement Model | Measurement Error | This diagram uses the dominant symbolic language in the SEM world. However, there are alternate forms, including the " RAM," reticular action model.

Latent Constructs
In structural equation modeling, the key variables of interest are usually "latent constructs"--abstract psychological concepts such as "intelligence" or "attitude." We can observe the behavior of latent variables only indirectly, and imperfectly, through their effects on manifest variables. A structural equation model may include two types of latent constructs--exogenous and endogenous. In the most traditional system, exogenous constructs are indicated by the Greek character "ksi" (at left) and endogenous constructs are indicated by the Greek character "eta" (at right). These two types of constructs are distinguished on the basis of whether or not they are dependent variables in any equation in the system of equations represented by the model. Exogenous constructs are independent variables in all equations in which they appear, while endogenous constructs are dependent variables in at least one equation--although they may be independent variables in other equations in the system. In graphical terms, each endogenous construct is the target of at least one one-headed arrow, while exogenous constructs are only targeted by...

...Introduction to StructuralEquation Modeling (Path Analysis)
SGIM Precourse PA08 May 2005 Jeffrey L. Jackson, MD MPH Kent Dezee, MD MPH Kevin Douglas, MD William Shimeall, MD MPH Traditional multivariate modeling (linear regression, ANOVA, Poisson regression, logistic regression, proportional hazard modeling) is useful for examining direct relationships between independent and dependent variables. All share a common format:
Dependent Variable = Independent variable1 + Independent Variable2 + Independent Variable3
The net result of such modeling is to examine relationships in the following format Independent Variable1 Independent Variable2 Independent Variable3 Dependent Variable
However, real life may not be so parsimonious, relationships between various variables may be much more complex, more “web-like,” for example: Independent Variable6 Independent Variable1 Independent Variable2 Independent Variable3 Dependent Variable
Independent Variable4
Independent Variable5
In this example, Variables 1-3 and 6 have direct effects on the dependent variable, while variables 4 and 5 have indirect effects, mediated by effects on Variables 1, 2 and 3. Variable 6 1
has both direct and indirect effects on the dependent variable. This "web" of relationships could not be easily modeled with standard regression techniques. On the other hand, structuralequation modeling (SEM) readily allows one to explore such...

* A Conceptual Overview

* StructuralEquation Modeling and the Path Diagram
A Conceptual Overview
StructuralEquation Modeling is a very general, very powerful multivariate analysis technique that includes specialized versions of a number of other analysis methods as special cases. We will assume that you are familiar with the basic logic of statistical reasoning as described in Elementary Concepts. Moreover, we will also assume that you are familiar with the concepts of variance, covariance, and correlation; if not, we advise that you read the Basic Statistics section at this point. Although it is not absolutely necessary, it is highly desirable that you have some background in factor analysis before attempting to use structural modeling.
Major applications of structuralequation modeling include:
1. causal modeling, or path analysis, which hypothesizes causal relationships among variables and tests the causal models with a linear equation system. Causal models can involve either manifest variables, latent variables, or both;
2. confirmatory factor analysis, an extension of factor analysis in which specific hypotheses about the structure of the factor loadings and intercorrelations are tested;
3. second...

Enterprise resource planning (ERP) and supply chain management (SCM) represent important information technology investment options for operation or IT managers, and have been acclaimed in the practitioner and academic literature for their potential to improve business performance. The purpose of this article is to provide further insights into the adoption of ERP systems and the impacts on ﬁrm competence in SCM. We propose a model featuring ERP beneﬁts to ﬁrm competences in supply chain management. We also hypothesize that three constructs of ERP beneﬁts positively impact ﬁrm competences in SCM. To clarify the relationships among these constructs, structuralequationmodel (SEM) is conducted to examine the model ﬁt and...

Abstract
Purpose This study aims to examine the causal relationships among fashion involvement, positive
emotion, hedonic consumption tendency, and fashion-oriented impulse buying in the context of
shopping.
Design/methodology/approach A self-administered questionnaire developed from the literature
was administered to 217 college students during a scheduled class. They were enrolled at one
metropolitan university in a southwestern state in the USA. A structuralequationmodel using a
correlation matrix with maximum likelihood was estimated by LISREL 8.53.
Findings Fashion involvement and positive emotion had positive effects on consumers’
fashion-oriented impulse buying behavior with fashion involvement having the greatest effect.
Hedonic consumption tendency was an important mediator in determining fashion-oriented impulse
buying.
Research limitations/implications This study was limited to college students at one
metropolitan university in a southwestern state in the USA and to general fashion products.
Practical implications Retailers may encourage consumers’ positive emotion through strategies
such as store design, product...

...Sigmund Freud’s structuralmodel of the psyche can be classified as three main parts that interrelate but not supersede each other. The components are named the id, ego, and superego. Each component has a distinct role in that leads to the development of a child’s structure of personality. The id is the uninhibited, natural, chaotic part of the personality. The ego is develops immediately after birth and one of its main responsibilities is to provide a balance between the desires of the id and the realities of the outside world. The superego represents the rights and wrongs that have been developed to the child by their parents, educators and other significant individuals. By my estimation about 80% of our psyche is unconscious. In terms of the structure of personality, sublimation can be defined as the id having an unwanted impulse and the ego balancing the desires of the id into socially approved thoughts, feelings, or behaviors.
There are types of parents, authoritarian, permissive, authoritative and uninvolved. Authoritarian parents are rigid and punitive. They are very strict and expect their children to be obedient. Permissive parents are very relaxed and lack direction. They are very warm but don’t require much from their children. Authoritative parents set limits and goals. They try to reason and explain things to their children. Uninvolved parents show little interest in their children. Usually these parents are emotionally detached...

...Anna Nicole Smith (born Vickie Lynn Hogan) (November 28, 1967 – February 8, 2007), was an American model, actress, and television personality. Smith first gained popularity in Playboy, becoming the 1993 Playmate of the Year. She modeled for clothing companies, including Guess jeans and Lane Bryant.
Smith dropped out of high school at age 15 and was married in 1985. Her highly publicized second marriage to oil business mogul, J. Howard Marshall, 62 years her senior, resulted in speculation that she married the octogenarian for his money, which she denied. Following Marshall's death, Smith began a lengthy legal battle over a share of his estate. Her case, Marshall v. Marshall, reached the U.S. Supreme Court on a question of federal jurisdiction, and again on a question of bankruptcy court authority (now called Stern v. Marshall). Smith died on February 8, 2007 in a Hollywood, Florida hotel room as a result of an overdose of prescription drugs. Within the final six months of her life, Smith was the focus of a renewed press coverage surrounding the death of her son, Daniel, and the paternity and custody battle over her newborn daughter, Dannielynn.
Smith announced on June 1, 2006, in a video clip posted on her official website that she was pregnant. "Let me stop all the rumors," she said, while floating on an inflatable raft in a swimming pool. "Yes, I am pregnant. I'm happy, I'm very, very happy about it. Everything's goin' really, really good and I'll be...
