Hi guys,
- I have stata IC 10
- I am conducting three-multilevel analysis let say
mixed y X1 X2 || student: || class: || school . In this regression X1 and X2 are statistically significant
Now I add X3 the regression becomes:
mixed y X1 X2 X3|| student: || class: || school
In this regression X2 is no longer significant. The same problem arised when I add more than one variable
Could you be please let me know what is the problem and how can I handle it
Many thanks for your time
Ayi Ayi
