 Posted: Tue Jun 10, 2008 2:10 am Post subject: compute sample correlation from correlations of sub-samples |
 |
|
Given a sample of, say, 10,000 observations, is it possible to compute
the sample correlation from the correlations of sub-samples? For
example, assume
correlation,observations
-0.05, 5000
0.15, 3500
0.87, 1500
Using only this data, can the correlation of the entire sample of
10,000 observations be computed?
Thank you. |

Have you tried sending this to the <sci.stat.math> news group?
