Drs. Muthen and Muthen,
I am running a LGC with 6 time points.

For context, School connectedness is a latent construct measured by 5 items.

When I view my results, I am confused because I keep getting my Mean of the i as 0, p = 999 and this does not seem right. I was wondering if I was coding something incorrectly?

Here is some of the code:
SC_G70 BY SC1_G70* SC2_G70 SC4_G70 SC5_G70 SC6_G70 (1-5);
SC_G75 BY SC1_G75* SC2_G75 SC4_G75 SC5_G75 SC6_G75 (1-5);
SC_G80 BY SC1_G80* SC2_G80 SC4_G80 SC5_G80 SC6_G80 (1-5);
SC_G85 BY SC1_G85* SC2_G85 SC4_G85 SC5_G85 SC6_G85 (1-5);
SC_G90 BY SC1_G90* SC2_G90 SC4_G90 SC5_G90 SC6_G90 (1-5);
SC_G95 BY SC1_G95* SC2_G95 SC4_G95 SC5_G95 SC6_G95 (1-5);
SC_G100 BY SC1_G100* SC2_G100 SC4_G100 SC5_G100 SC6_G100 (1-5);


SC_G70@1.0 ;

i s | SC_G70@0 SC_G75@.5 SC_G80@1.0 SC_G85@1.5 SC_G90@2.0
SC_G95@2.5 SC_G100@3.0;

[SC_G70@0]; !fix latent means to 0

(This is truncated, I also correlate the items residuals over time).
Thank you for your help!
Nicole
