In contrast, variations in glycopeptide use followed variations in %MRSA with an average delay of 1 month (coefficient = 0.45).
For recapture (as a proxy for survival), initial exploration of competing models of the data (n = 1,360) showed a clear pattern in the sign of the coefficients of different months, which were positive from July through October but negative or zero from November through June, with the exception of April (coefficient = 0.068, standard error [SE] = 0.56).
The fact that a consistent causal connectivity map is available in addition to the caused connectivity map, is a significant advantage of using the MAR coefficient norm metric.
The results of this preliminary investigation show that the use of the MAR coefficients directly provides a meaningful functional network of causality.
As it can be seen from Eq. (19) for a given voxel pair i− j and frequency, the element is in effect the z-transform of the MAR coefficients series across time lags a ij, modeling the effect of voxel j on voxel i.
To test the null hypothesis that duration to MM has no impact on an outcome, we tested the hypothesis that all of the mail-month coefficients are zero.
Using previous notation, θ ^ m is the MAR estimated logistic regression coefficient of genotype 3 in the imputed dataset m = 1,…,M.
The correlation was strongest for the HLPC scale score and satisfaction with the GP in the last 12 month, resulting in a correlation coefficient of 0.47.
Test-retest reliability was analysed for 44 outpatients who declared that their general health status due to osteoporosis had not changed after a month, with an Intraclass Correlation Coefficient of 0.80 and a mean (SD) score change of 0.2 (0.5) points.
Adding interacted variables markedly shrinks both coefficients, the March coefficients becomes even negative (see March and April effects in columns 2 and 3 of Table 8).
