41. If two random variables are subindependent, and if their covariance exists, then they are uncorrelated . 42. The visual distortion can cause uncorrelated images to stimulate corresponding retinal regions simultaneously impairing fusion of the images. 43. Correlations may be positive ( rising ), negative ( falling ), or null ( uncorrelated ). 44. While the overall constraints are inconclusive, uncorrelated isocurvature cold dark matter modes are found to be unlikely. 45. A value of 0.5 indicates the data is uncorrelated or has only short-range correlations. 46. The histogram is then normalized with respect to an ideal gas, where particle histograms are completely uncorrelated . 47. By investing in many small positions, losses can be minimized, as long as positions are uncorrelated . 48. With N-th root process, the suppression of uncorrelated noise is better than with linear beamforming. 49. Exclusion of birthplace, together with the assumption that \ epsilon is uncorrelated with education produces a misspecified model. 50. Similarly, random vectors whose covariance matrix is zero in every entry outside the main diagonal are called uncorrelated .
