Path Analysis Introduction and Example
Path Analysis Introduction and ExampleJoel S Steele, PhDWinter 2017 Path AnalysisModel specificationThere two main ways of communicating the system of equations that represents a theoretical model. Eitherwith a set of simultaneous equations, or with a path diagram. Below we explore both and provide an Model AssumptionsFor this Example we will be accepting a number of All causal relations arelinearandadditive2. All models are recursive results in uncorrelated error terms notwo-waycausal relations no feedback loops3. Error terms are uncorrelated with other independent variables4. There is aweakcausal ordering5. Causal closure, meaning all of the relevant causal variables are included in the modelIf these assumptions are met, then we can use least squares regression for our estimation.
