Weighted - average correlation coefficients between equivalent pairs of SDQ and Child Behavior Checklist subscales11 from 9 parent - reported studies were uniformly strong and positive (range: 0.52 < r < 0.71).10 Several studies showed strong correlations between SDQ subscales and «real world» outcomes such as clinical diagnoses (criterion validity); SDQ scores identified school - aged children with concurrent behavioral and emotional disorders, including attention - deficit / hyperactivity disorder (ADHD) and autism spectrum disorder / Asperger syndrome (ASD / AS), and predicted their occurrence 3 years later.4, 12,13 However, multitrait - multimethod analyses have not provided consistently strong evidence of discriminant validity of the school - age SDQ subscales.

Correlations were then transformed using Fisher's Z for all subsequent analyses, as recommended when averaging correlation coefficients (Silver and Dunlap 1987).

In order to illustrate how relative similarities of responses in each brain region varied as a function of social distance, inter-subject time series similarities (i.e., Pearson correlation coefficients between preprocessed fMRI response time series) were normalized (i.e., z - scored across dyads for each region) prior to averaging across dyads for each brain region within each social distance category.

In order to illustrate how relative similarities of responses in each brain region varied as a function of social distance, inter-subject time series similarities (i.e., Pearson correlation coefficients between preprocessed fMRI response time series) were normalized (i.e., z - scored across dyads for each region) prior to averaging across dyads for each brain region and overlaying results on an inflated model of the cortical surface for each social distance category.

Thus, in the calculation of the average correlation matrix, the denominator was adjusted for the number of all valid correlation coefficients at each element of the matrix.

I've added a small essay from 2 years ago questioning whether correlation coefficients can be used on averaged data (yearly, monthly, weekly, daily).

Panel (a) shows the CR flux (red line) from combined Moscow and Climax neutron monitor data, and the globally averaged ISCCP IR low (> 680 mb / < 3.2 km) cloud anomaly plotted at a monthly resolution from June 1983 to December 1994, (b) shows the local correlation coefficient (r - values) achieved between the cloud and CR flux data for 12 - month (boxcar) smoothed values.

For low cloud cover, only the solar proxies, GCR proxies, the AMO, PDO, and ENSO exhibit significant correlation coefficients, and no correlation variable satisfies the rcritical for cloud cover when averaged over the entire domain.

In fact the Mauna Loa or global CO2 rise is much faster than linear... the differences between the mauna loa / global are negligible for the purpose of radiative transfer, and the difference in average CO2 concentration between an «average global» data - set and the Mauna Loa record since 1980 (for monthly values) is only 0.65 ppm (and with a correlation coefficient r greater than 0.99) indicating that the Mauna Loa record is representative of global - scale CO2 concentration as you'd expect with a well - mixed gas.

Pearson and ICC between AQoL - 8D and other MAU instruments resulted in above average coefficients, with the former technique and the highest average correlation using the ICC; however, differences were generally small.
