Longitudinal data analysis as general linear mixed effects modeling using restricted maximum likelihood and assuming exponential spatial correlation between measurements (strength of which depending on the length of the time interval between measurements) was used to analyze the effect of age, treatment, time and blinding on the quality of life.
GLS models were fitted by maximum likelihood and with a Gaussian spatial correlation structure in cases of multiple predictors.
The clustering around the spikes (local maxima) can be attributed to the spatial correlation among adjacent transmitters.
This result implies that an upper bound on the maximum diversity is the sum of the maximum diversities in each separated path, and the maximum diversities in each path are affected by the spatial correlation of the links between the transmitter and the receiver across different paths and the channel temporal correlation.
The spatial correlation difference between minimum and maximum 's has now been increased, since the vector is closer to the resultant than the vector is to.
The impulses from the sensors are detected at the FC through an optimum multi-node maximum a posteriori (MAP) detector, which exploits the spatial correlation among the signals from the sensors.
Semi-informative priors were set for the rate of decay of spatial correlation, φ, informed by the maximum and minimum distance between schools, and non-informative priors used for other coefficients.
The maximum diversity of SF-coded MIMO-OFDM systems with arbitrary spatial correlation was studied in [16].
We then jointly reestimated the parameters of interest quantifying the covariate effects, β0,... β n, with the exponential spatial correlation parameters (range, sill, and nugget in geostatistical terminology) using maximum likelihood, yielding GLS estimates for covariate effects (Diggle et al. 1998b).
By modifying the distance among network nodes and antennas, they characterized the effect of spatial correlation and subspace distance and showed that IA is able to achieve the maximum available degrees of freedom (DoF) over realistic channels.
