A more subtle limitation of the expectation-variance model is that its output is a binary variable – the absence or presence of an alarm.
However, we were underwhelmed by the power of tracking approaches to detect more subtle differences in behavior that might explain variance in neural firing collected during our experiments.
The remaining 18% of the variance is explained by the four remaining components, which represent more subtle shifts in activity that are less easily rationalized by intuitive chemical arguments.
Moreover, averaging across voxels from one tract reduces the variance in diffusion measures and thereby increases the power to detect more subtle changes in white matter structure.
However, sodium excretion as well as measured CCrea are subject to a high variance, at least in clinical situations, and thus may be too insensitive to detect more subtle renal dysfunction.
Such subtle variances in flavor are also a Jewish tradition.
The connection is more subtle.
