latent variable score
hii
1)plz say me how to compute latent variable score with hand,i want to compare with result of pls.
2)lisrel and pls compute latent variable score in diffrent ways or with same formula????

Hi,
LV = w1 * MV1 + w2 * MV2 + ... + wn * MVn
Where MV are the manifested variable (indicators) after standardization [(Xi – Mean) / Standard Dev]
and wn are the outer weights.
After compute LV you should to standardize the LV scores to have the “standardized LV socres”, with mean = 1 and s.d. = 1
If you want to compute the LV scores unstandardized follow: viewtopic.php?t=812

Hi,
PLSPM is consistent and consistente at large = as sample size and the number of indicators by LV increase > the results of PLSPM tend to be equal the results of LISREL.
LISREL is covariance based = the relations are computed from LV to the indicators, the last thing to be computed are the scores of LV.
PLSPM is variance based = the relations are computed from indicators to the LV, the first thing to be computed are the scores of LV.
For these reasons, the correlation between scores computed by LISREL and scores computed by SmartPLS should be high, but they will not be the same.
For example (p.192):
Tenenhaus, M., Esposito Vinzi, V., Chatelin, Y.M., & Lauro, C. (2005). PLS path modeling. Computational Statistics & Data Analysis, 48(1), 159205. doi:10.1016/j.csda.2004.03.005

for reflective model,how to compute LV score?
but i remember what you said before,the lv scores(original) SMARTPLS computed are not correct? i need compute them by hand?Diogenes wrote:Hi,
in the same way, use the "outer weights".
SmartPLS already computes the LV scores, see::
Report / PLS / Calculation results / Latent variable scores /

Re: latent variable score
hi
i'm new in PLS and i have a model that i wanna run with pls3.
in my model i have a latent variable that must calculate from 4 other latent variable. in lisrel it could compute latent variable from other latent variable without any indicator but in pls when i want to do such thing it warn me that your model is invalid. is there any way so i can calculate this latent variable is pls?
