Dependency of univariate model coefficients for depressive mood on different time frames.

<p>The estimated values of the univariate model coefficient for depressive mood scores are shown in a colored matrix form consisting of 25 rows (different locations) and 12 columns (different sizes). Each grid cell indicates some specific location and size of a time frame used for calculating the local statistics of locomotor activity. A color in each cell represents the value of the model coefficient (γ₁₀) of the predictors: (a) Mean, (b) Skewness, and (c) Detrended skewness. False discovery rate with a <i>q</i> value of 0.05 was used as the multiple comparison adjustment. Only significant cases are shown by colors. Color bars indicate the value of the model coefficient. Note that the univariate model used for the analysis is as follows; Depressive mood score_<i>ij</i> = γ₀₀ + γ₁₀ (Local statistics of locomotor activity_<i>ij</i>) + ζ_0i + ε_<i>ij</i> (see Results for details).
