Hello,
im currently working on my master thesis and i have the problem that the r² value of my dependent variable is too low (0,410).
But due to the predictive research in my master thesis i want to increase the r² value of my dependent variable to 0,710.
But how?
Thanks for any advices!
how to improve r square?

Hi,
1st idea) With more predictive LV, maybe the R2 will increase.
For instance, in ECSI studies:
2 predictors --> 44% < R2 (mean) < 52%
3 or 4 predictors --> 67% < R2 (mean) < 79%

TENENHAUS, M.; VINZI, V. E.; CHATELIN, Y.; LAURO, C. PLS path modeling. Computational Statistics & Data Analysis, v.48, p.159-205, 2005.
2nd idea) Using AMOS or LISREL (covariance based) there is a tendency of structural results to be bigger than PLS-PM.
