[ODP] The international general socioeconomic factor: Factor analyzing international

#22
Hi Meng Hu,

Quote:I agree with you concerning the countries, sometimes naming them is awful. I always hated to work with national data. I once (2 years ago) gathered large amount of data notably GDP, economic freedom indices, and savings for all years and diverse sources, but screwed up at the end with the rows that don't match. I gave up completing the data set since then. It's lot of stress and I don't need that. However, can you send me (by mails, preferably) the data sets before they are matched using the procedure you describe ? I just want to see if the matching/merging are correct.

It is easy to verify that it works. You can just create some datasets and merge them yourself. The code is open source, so it is available to anyone who can figure out how to install Python (use the Anaconda package).

You can also merge some actual datasets, e.g., different measures of inequality. Wikipedia has lots of these national rankings for all kinds of stuff.

Quote: I have problem with that. When you say "one of us" you refer to [2] a study by Kirkegaard and Fuerst. That seems confusing to me.

It was because when I wrote the paper, I had imagined that I would have a co-author. I ended up doing all the analyses myself, so there is no co-author. For that reason, some of the language was off, e.g. using "we", "our". You found another remnant of that. I have fixed it.

Quote:In that case shouldn't it be "national-level" instead of "group" level ?

The group level versions are capitalized. The national-level versions are a subset of group-level versions. For instance, in my previous paper on immigrant groups in Denmark, it was group-level but not national-level.

Quote: Do you know what is the recommended ratio ? I think you should say it explicitly, as it would help some people lost here (like me).

Since you use KMO, why not add a little sentence about what it is ? See Andy Field book "Discovering statistics using spss: Introducing statistical method" (p647).

Another alternative is to use the Kaiser–Meyer–Olkin measure of sampling adequacy (KMO) (Kaiser, 1970). The KMO can be calculated for individual and multiple variables and represents the ratio of the squared correlation between variables to the squared partial correlation between variables. The KMO statistic varies between 0 and 1. A value of 0 indicates that the sum of partial correlations is large relative to the sum of correlations, indicating diffusion in the pattern of correlations (hence, factor analysis is likely to be inappropriate). A value close to 1 indicates that patterns of correlations are relatively compact and so factor analysis should yield distinct and reliable factors. Kaiser (1974) recommends accepting values greater than 0.5 as barely acceptable (values below this should lead you to either collect more data or rethink which variables to include). Furthermore, values between 0.5 and 0.7 are mediocre, values between 0.7 and 0.8 are good, values between 0.8 and 0.9 are great and values above 0.9 are superb (Hutcheson & Sofroniou, 1999).

The answer is: There are lots of different recommendations. Read the source I refer to, you will like it.

[11] Nathan Zhao. The minimum sample size in factor analysis, 2009. URL https://www.encorewiki.org/display/~nzha...r+Analysis

I have added a short explanation of KMO and Bartlett's test.

My rewording:

I performed principle components analyses (PCA) on both the reduced and the means-imputed datasets to examine the effect of the procedure. The correlation of factor loadings was 0.996 indicating that the procedure did not alter the structure of the data much. I performed KMO tests (a measure of sampling adequacy) on both samples which showed that reducing the sample reduced the KMO (0.899 to 0.809). In comparison, KMO in the DR dataset was 0.884. All values are considered ‘meritorious’.\cite[p. 225]{hutcheson1999multivariate}

Bartlett's test (tests whether the data is suitable for factor analysis) were extremely significant in all three datasets (p$<$0.00001).


Quote:I do not understand what's in bold.

It means that I did the random sampling 1000 times in my R code. Or in other words. 1000 times I picked N number of random variables, performed a factor analysis on the data with those variables, and then correlated the scores from the first factor from this analysis with the those found from the analysis of all variables.

Quote: The word "causation" is too strong. Given the annoted references, only 20 and 21 talk a little bit about causation, but that's not even clear there is strong evidence for this pattern of causation. Instead, there is evidence that the causation wealth->IQ is not well established. Perhaps my best conclusion is that it would be best to argue, at least for now, that we don't have strong evidence for either of these two pattern of causation (i.e., wealth cause IQ or the reverse). You can argue there is probably some very indirect suggestion that IQ causes wealth more than the reverse, as your articles on immigrations, notably with John, seems to show this, but as i said, it's very indirect proof.

It is well-established at the personal level that the causation is g→wealth (income), not much the other way. At the national level, it is more contentious. I don't have to argue for that here, since I'm not making such a claim in the paper.

Quote:Even if G is not causal here, aggregation would also improve the correlation, no ?

Yes. It is a statistical phenomenon (cf. Spearman Brown formula).

Quote:I think table 2 should better be made as the table 1.

What do you mean? There is a table called "Table 1". It is in section 5.

Quote:Not related, but can you tell me how you manage to generate the nice graph at figures 2-5 ? Concerning the figures 2-5, again, have you contacted Major and his co-authors to ask for opinion ? I bet he (they) will be very interested.

Yes. Look in the file Loadings analysis.ods. It is just made with LibreOffice.

I have not contacted Major et al. His email is J.T.Major@ed.ac.uk. Perhaps we should contact him. He could be an external reviewer (journal policy is that authors are allowed to recruit one external reviewer).

---

Here's a new version. I have made the small change noted above and fixed some other small issues. Due to a wrong setting in LibreOffice, the previous results figures were a little bit off. There were some slight errors with the names of some references (involving use of italics in their titles).
