Exam 22: Primer on Structural Equations Modeling

Which technique allows a researcher to build and test a theory represented by a series of regression equations,each involving multiple item measures that are solved simultaneously?

The χ² test is completed by examining the computed value with the critical value of the t-distribution for the appropriate number of degrees of freedom.

A parameter that will be estimated by the SEM procedures is said to be ____.

Partial least squares (PLS)is only able to provide reliable results when there is large amounts of data.

A statistical technique that measures objects in multidimensional space on the basis of respondents' judgments of the similarity of objects is ____________________.

If the CFI is close to 1,the model is considered a relatively good fit.

____________________ is an interdependence technique that is often based on respondents' judgments of how similar different objects are on several characteristics.

Which technique is particularly useful when the measurement quality is not strong?

Which element assesses how well a theory meshes with reality by comparing the theoretical covariance matrix with the observed covariance matrix?

Explain the root mean square error of approximation (RMSEA)and how it is used to determine fit.

Partial least squares (PLS)originated in the physical sciences.

Which method is an example of an interdependence analysis?

Unlike SEM,partial least squares (PLS)does not provide a test of fit and is not a covariance-based technique.

A multivariate technique that combines a PCA-based factor analytical approach with a least squares based regression approach is ____________________.

The comparative fit index (CFI)can range from -1 to +1.
