FIMIX PLS segments and MGA
Posted: Thu Aug 13, 2020 1:21 am
Dear everyone,
I have a model for identifying factors affecting environmental perception, and have divided the data (total number is 184) into two groups (group1 is 105 and group 2 is 79) based on different scenarios.
The MGA results shown that there are no significant differences between the path coefficients of the two groups, but through Bootstrapping, three path coefficients are significant in group 1, and one path coefficient is significant in group 2. It seems quite strange.
After read several articles, I realized maybe the unobserved heterogeneity effect existing in this study. And I try to run the FIMIX
The result of FIMIX with the total data shows that
one segment
AIC (Akaike's Information Criterion) 1455.5378
AIC3 (Modified AIC with Factor 3) 1466.5378
AIC4 (Modified AIC with Factor 4) 1477.5378
BIC (Bayesian Information Criteria) 1490.9021
CAIC (Consistent AIC) 1501.9021
HQ (Hannan Quinn Criterion) 1469.8714
MDL5 (Minimum Description Length with Factor 5) 1720.3593
LnL (LogLikelihood) -716.7689
EN (Entropy Statistic (Normed))
NFI (Non-Fuzzy Index)
NEC (Normalized Entropy Criterion)
two segments
AIC (Akaike's Information Criterion) 1430.1663
AIC3 (Modified AIC with Factor 3) 1453.1663
AIC4 (Modified AIC with Factor 4) 1476.1663
BIC (Bayesian Information Criteria) 1504.1098
CAIC (Consistent AIC) 1527.1098
HQ (Hannan Quinn Criterion) 1460.1366
MDL5 (Minimum Description Length with Factor 5) 1983.8839
LnL (LogLikelihood) -692.0832
EN (Entropy Statistic (Normed)) 0.7751
NFI (Non-Fuzzy Index) 0.8234
NEC (Normalized Entropy Criterion) 41.3877
Segment 1: 0.8851
Segment 2: 0.1149
Here are my questions:
1. Should I redivide the data into two analysis groups based on the results of FIMIX? But I don't know which data goes into group one and which goes into group two. And if I do that, how do I compare the data between different scenarios?
2. I have read in the link viewtopic.php?f=12&t=16122&p=26942&hilit=fimix#p26942 that if I'm already known my groups, maybe I don't need to run FIMIX. Therefore, how can I interpret this strange result, or identify potential heterogeneity?
