The mean variance of lag-time TTO is higher in both the 15-year time frame (p < 0.001) and the 20-year time frame (p < 0.001).
Explained variance of first lag (and following lags) was too low to conclude that there was any predictability in IRTs.
Explained variance of the first lag was generally very low and not significantly different between the groups (0.08 > mean R2 > 0.05).
Explained variance of the first lag was generally very low and not significantly different between the groups (0.06 > mean R2 > 0.12; median R2 = 0.06 for ADHD, and 0.16 > mean R2 > 0.02; median R2 = 0.1 for comparisons).
Few of these investigations have controlled for synchronous correlations, an important source of extraneous variance in lagged associations, which may have confounded conclusions of prior investigations.
An analysis of variance showed a significant effect of lag on mean visibility ratings in T2-present trials, F 5, 50) = 7.0, p = .009.009
Bollerslev (1986) extended the ARCH model based on the assumption that forecasts of the time-varying variance depend on the lagged variance of the variable under consideration.
Only one minor repeated QTL for a berry acidity trait was detected twice in Picovine, at the top of LG 5, explaining 6%to12%12 % of the total berry acid concentration (ToAG) variance at green lag phase.
This relation was tested by correlating first lag explained variance of all spatial measures with normalized scores on Grooved Pegboard test and Mazes (see Meyer & Sagvolden for details) for both dominant and non-dominant hand, for the ADHD-C group and the non-ADHD group separately.
To avoid correlation generated by several lagged values of the same variable (which can bias estimated variance of calculated coefficients), only 1 lagged version of a given explanatory variable was kept.
For small lags, the variance of the estimates is small, but the estimation is highly biased.
