HW #1
DATA: (For JMP) org_hw1.jmp
(For SAS) org_hw1.sas7bdat in shared directory SEM (create library SEM)
See the description of the data on the next page.
Part One: SEM Using JMP
Prerequisite: Read JMP exercises in Lab note pp.191-193
You need to know how to specify/build and run the model.
Q1 Specify and run a structural equation model based on Figure 1 (page 3).
Save the results in the data table and rename it as HW1-name.jmp to submit it.
Part Two: SEM Using SAS
Prerequisite: We have discussed the Math Attitude example in class.
Read SAS_CALIS_SEM.pdf and run sas-sem-stem.sas (Hybrid Online)
You need to check PROC CALIS model commands.
Q2 Write the SAS code to specify the model based on Figure 1.
(you can start from sas-sem-stem.sas and change for the new data and model)
Q3 Based on the Q1 output, (i) evaluate the model fit, and (ii) briefly interpret the three unstandardized path coefficients (Parameter Estimates -> Regressions).
Submit your answer in a Word file.
Data Description
This example is part of the survey data used in Bergami and Bagozzi (2000), which consists of a sample of 305 employees (male = 157 and female = 148) from the electronics division of a large conglomerate in South Korea. From the original data, the example includes 21 indicators associated with four latent variables, called organizational prestige, organizational identification, affective commitment (joy), and affective commitment (love). These indicators (in regular font) and latent variables (in boldface) are presented in Table 1. Figure 1 displays a structural equation model specified for the example.
Table 1. Twelve indicators (in regular font) for four latent variables (in boldface) were taken from Bergami and Bagozzi’s (2000) organizational identification data.
