Code 1
latent variables
ind60 =~ x1 + x2 + x3
dem60 =~ y1 + y2 + y3 + y4
dem65 =~ y5 + y6 + y7 + y8
regressions
dem60 ~ ind60
dem65 ~ ind60 + dem60
residual covariances
y1 ~~ y5
y2 ~~ y4 + y6
y3 ~~ y7
y4 ~~ y8
y6 ~~ y8
Code2
latent variables
ind60 =~ x1 + x2 + x3
dem60 =~ y1 + y2 + y3 + y4
dem65 =~ y5 + y6 + y7 + y8
regressions
dem60 ~ alpha*ind60
dem65 ~ direct*ind60 + beta*dem60
effects of interest
indirect := alpha * beta
total := indirect + direct
proportion := indirect/total
residual covariances
y1 ~~ y5
y2 ~~ y4 + y6
y3 ~~ y7
y4 ~~ y8
y6 ~~ y8
