Thus, genes with correlated time-dependent expression patterns are likely to be involved in functionally related cellular processes.
Let us consider an ARMA p,q) time-series with correlated innovations at time instant t, i.e., x_{1 t}= A_{t}^{-1} B_{t} u_{1 t} ;, qquad u_{1 t}sim mathcal{N}left 0, sigma_{u}^{2} R_{u_{t}}right).
Further discussions cover several important and often overlooked topics, including the relationship between parameter identification, uncertainty analysis, and optimization in hydrological modeling, how to deal with correlated parameters, and time-varying SA.
When ({mathcal {L}}=Delta) and B is a fractional noise in time with correlated spatial structure, Tudor and Xiao [22] studied various path properties of the solution process u with respect to the time and space variable.
Time spent playing playground games was significantly positively correlated with time in VPA, with an only slightly less strong correlation with time spent in MVPA.
Notably, time observed being very active was significantly positively correlated with time in MVPA and in VPA (and negatively correlated with time spent sedentary).
Our objective is to sequentially infer the evolution of a latent time-series with correlated innovations, as we acquire new observations.
The outcomes of the stratified log-rank test (1), the modified log-rank by Schoenfeld and Tsiatis for highly stratified data (2) and the Cox model with sandwich variance that accounts for stratified data with possibly correlated failure times (3) are reported.
In the upper side of the S-shape we identified hypoxanthine and alanine strongly positively correlated with time, together with choline/phosphocholine, myo-inositol, creatine, and total glutathione.
