When parallel tests are absent, one option is to rely on hypotheses such as that the test parts are essentially tau-equivalent or congeneric, having only one factor in factor analysis. Such hypotheses are unrealistic, except that a test may be congeneric when there are only three test parts;...
Subjective probabilities play an important role in marketing research, for example where individuals rate the likelihood that they will purchase a new developed product. The tau-equivalent model can describe the joint behaviour of multiple test items measuring the same subjective probability. In this pa...

The tau-equivalent model can describe the joint behaviour of multiple test items measuring the same subjective probability. In this paper we stress the use of confidence intervals to assess reliability, as this allows for a more critical assessment of the items as measurement instruments. To ...
The results provided evidence for a good fit of a tau-equivalent model. Furthermore, multi-group CFAs provided support for strict measurement invariance of this model. To the Authors' knowledge, it is the first practical application of a tau-equivalent model to testing the factorial validity of...
We obtain conditions which are necessary and sufficient for the existence of a probability measure Q equivalent to P (which we call an equivalent [tau]-measure) such that each of the d component sequences of (X(n)) has a prescribed martingale property w.r.t. Q (i.e., it is either ...
