Third, on a task requiring high-level controlled processing (follow a target that randomly moves across the computer screen), preschool children at risk for ADHD were disproportionately more inaccurate and variable compared to healthy controls, children with borderline ADHD, and children with other psychopathology [ 7].
The limitations of gradient-based methods are; high development cost, noisy objective function spaces, inaccurate gradients, categorical variables, and topology optimization [285].
Although observational studies provide data on real world patients in real world settings, they are subject to potential bias by selection, confounding, survivor bias, and inaccurate measurement of variables.
Moreover, data have accumulated which suggests that hyperuricemia plays a role in the occurrence of hypertension, heart disease, type 2 diabetes and renal impairment [ 4], which would make traditional statistical adjustments for confounding variables inaccurate.
One common assumption in regard to the motor behavior of handicapped people is that they are different from the so called normal individuals, difference that is invariably taken as synonymous of the handicap individual being slower, more variable, inaccurate, and inefficient than their normal counterpart.
They confirmed the limited, inaccurate and highly variable data obtained from urinary creatinine collections to quantify the GFR.
Such specific, rapid, and uncontrolled degradation of the Cy5 dye results in inaccurate and highly variable gene expression measurements.
Second, the many subjective factors and inaccurate weights assigned to variables make the measurement model difficult to generalize and apply to other contexts (Bruneau et al. 2003; NRC 2012).
Unfortunately, low solubility affects bioassays by causing underestimated activity, reduced HTS-hit rates, variable data, inaccurate SAR, discrepancies between enzyme and cell assays and inaccurate in vitro ADME Tox testing.
