What are path coefficients in SEM?

A path coefficient indicates the direct effect of a variable assumed to be a cause on another variable assumed to be an effect. Path coefficients are standardized because they are estimated from correlations (a path regression coefficient is unstandardized). Path coefficients are written with two subscripts.

What is the difference between Amos and SPSS?

IBM SPSS Amos is a software program used to fit structural equation models (SEM). Unlike SPSS Statistics, SPSS Amos is only available for the Windows operating system. Amos is technically a “standalone” program: it can be installed and used without having SPSS Statistics installed on the machine.

What is the difference between SEM and path analysis?

How is path coefficient analysis calculated?

1 = P2R4 + P214 + P224 + P234 + 2P14r12P24 + 2P14T13P34 + 2P24r23P34. P2R4 is the square of residual effect = 0.6224. Path coefficient analysis revealed that the direct contribution of total number of capsules/plant was high and positive (P24 = 0.6320) which was followed by seeds/capsule (P34 = 0.4090).
