The terms of use of the ISPCR are: "You agree not to redistribute data or other materials without the written agreement of ICPSR". I don't think they would grant someone the ability to upload the data elsewhere.

I understand and condone the policy of the journal. However, I forsee others running into the same problem. Many of the data files used by researchers are under similar, often more limiting, restrictions (e.g., ADD Health). In thge case of Project Talent the data is available just three clicks away.

I appreciate the comments and especially editing and help with the MCV. Curt

It's sad thing if it cannot be published here. It's a known fact that this kind of data are not destined to be shared. The problem is with the institution.

But I can see another alternative. If publication of raw data is not possible (even only for the variables considered in the study) why not publish the correlation and covariance/variance matrix, along with the mean scores of those variables instead ?

If you only publish covariance, even this can be quite useful. For example, with covariance/variance matrix (+mean and SD) you can perform MGCFA, but also SEM and other path analyses. That can be very helpful.

EDIT : that's with the use of covariance matrix that some people like Briley and Beaujean succeed to publish the following papers :

.Explaining the Increasing Heritability of Cognitive Ability Across Development: A Meta-Analysis of Longitudinal Twin and Adoption Studies.

.Heritability of cognitive abilities as measured by mental chronometric tasks: A meta-analysis.

EDIT (2) :

The data is just there

I look at it and found the variables Dunkel used, for example, the question "HOW WELL DOES PARENT SPEAK HEBREW OR YIDDISH" has the variable label "BY_SI062". I can see it's a big data.

I know. But I just wanted to ask if the author can share the covariance/variance matrix (+ mean and SD) instead of the raw data if the latter is forbidden. It is feasible or not ?

Here is the updated version. It is not substantially different from the last uploaded version, the only differences is that a few typos were corrected.

Yes, I do.

Publish

Here is the final edited version.
