Lago-Médez and colleagues [ 16] correlated DFS sum scores with Corah's original DAS, finding evidence for the construct validity of the DFS.
In a sample of patients with osteoarthritis, on the other hand, Rosemann and colleagues found that female gender and age were weakly positively correlated with PACIC sum scores, while education was slightly negatively correlated with them.
The categorical predictor carry, which is highly correlated with unit sum, failed to explain a significant amount of additional variance.
Scores were calculated as a weighted count of correlated substitutions, by summing the inverse branch lengths between organisms when both residues had changed since the LCA.
Estimated beta values of the insula and OFC were extracted clusterwise via the first eigenvariate and correlated with DFS sum scores and tonic and phasic SCRs towards auditory symptom provocation within the DP.
With respect the total variance (9), if the total variance, instead of the true score variance, is assumed to be fixed, Var(S) is an increasing function of ρ, which conforms to an elementary statistical theory that variance of sum of correlated variables increases with increasing correlation.
The efficient probability analysis method is extended for the sum of correlated non-normal random variables with correlation coefficients expressed by the power of a common value.
Optimal allocation designs for the allocation proportion are obtained in the present paper for a two-treatment situation, in a completely correlated setup where the sum of the responses no longer follows a binomial distribution.
where b s ( k ) represents the sum of correlated errors which generally include tropospheric error, ionospheric error, and ephemeris error, while ε ρ s ( k ) represents all uncorrelated errors following a Gaussian distribution.
'Overall quality of life' (QLQ-C15-PAL) and POS sum score correlated highly (r = −.59, p < .01).01
The k correlated items are often summed up to a scale that is intended to measure the target construct.
