Hi every one!
I would like to know if some one of you could help me to understand what exactly a indeterminacy problem is?
I've read this in one article:
"The use of PLS has certain advantages:
• It does not suffer from indeterminacy problems like other causal modelling
techniques using EQS or LISREL"
Thanks
Dora

Hi,
as common factor analysis, there is no unique solution to generating the factor scores, a situation known as factor score indeterminacy.
in PLS (and principal components analysis) the LV is a exact linear combination of its indicators.
For more details, see:
NUNNALY, J. C.; BERNSTEIN, I. H. Psychometric Theory. 3rd Ed. Mc-Graw Hill, 1994, p. 509.
PETT, M. A.; LACKEY, N. R.; SULLIVAN, J. J. Making sense of factor analysis: the use of factor analysis for instrument development in health care research. SAGE, 2003, p. 215.
FORNELL, Claes; BOOKSTEIN, Fred L. (1982). Two structural equation models: LISREL and PLS applied to consumer exit-voice theory. JMR, Journal of Marketing Research, v.19, n.4.,p.449.
