SmartPLS is a software application for (graphical) path modeling with latent variables (LVP). The partial least squares (PLS)-method is used for the LVP-analysis in this software.

3. Goal
Showing the student the main properties of SmartPLS
software used for basic statistical treatments.
1 part
Overview of the situation and presentation of the software.
2 part
Video showing how SmartPLS works
5. Overview of the presentation
• Intro
•Path diagram
•Software
•Worked Example
•Data collection
•Model design
•Hypotesis
•Simulation and parameter estimates
•Overview of the results
6. Refresh
• Correlation
– linear relationship between two variables
– range from -1 to +1
• Covariance
– unstandardised form of correlation
– positive number positive relationship
7. • Latent variable
– not measured directly in a study
– assumed to bring about the observed responses
• Observed variables
– directly measured in a study
• Exogenous variables
– assumed to be external to the model
– only have double headed arrows (i.e., correlation)
• endogenous variables
– predicted by other variables in the model
– directed arrow entering into them

36. Coeff definition review
•AVE
• average value
•Reability
•equal factor loadings misured
• variance portion rapresentation
•Composite reability
•overall reliability of a collection of heterogeneous
•R square
•coefficient of determination, measuring the amount of variation
accounted for in the endogenous constructs by the exogenous
constructs
•Cronbach’s α
•lower-bound estimate for the composite score reliability
37. Trust field
•Reliability: This is demonstrated by Composite
Reliability greater than 0.700.
•Convergent Validity: This is demonstrated by loadings
greater than 0.700, AVE greater than 0.500, and
Communalities greater than 0.500
•Discriminant validity: This is demonstrated by the square
root of the AVE being greater than any of the inter-
construct correlations.
