Effect of

variance ratio on ANOVA robustness: Might 1.

The heritability,

variance ratios for permanent environmental effect of ewe and residual

variance ratio were higher in this case (Models 3 vs Models 4).

Specifically, we adopt normalized Hasbrouck's (1993) intraday pricing error volatility, absolute value of first-order autocorrelation in daily returns, and absolute value of weekly to daily

variance ratio as our empirical measures of price inefficiency.

Lo and MacKinlay (1988) proposed using a

variance ratio test which is based on comparing variance estimators derived from data sampled at different frequencies.

Second, the replenishment rule has an impact on the inventory stability (as measured by the inventory

variance ratio, i.

The GCA/SCA

variance ratio exhibited that all the traits were under control of non-additive type of genes except plant height, which was found equally under control of additive and non-additive genes.

The design for the five group simulation study was 4 x 3 x 3 x 5 completely crossed design with (a) four levels of skew, (b) three levels of sample size, (c) three levels of sample size ratio, n1/n2/n3/n4/n5, and (d) five levels of

variance ratio.

Ranks and signs-based multiple

variance ratio tests.

This negative effect was more obvious when

variance ratio was 1:1:10 for k=3 and 1:1:1:10 for k=4(Table 3 and 4).

When estimating the health effects related to a chemical exposure, the

variance ratio (i.

Additionally they examine two performance metrics for assessing the bullwhip effect: the order rate

variance ratio and the net stock amplification.

A number of statistical tests comprising Ljung-Box Q statistics test, Runs test, GARCH volatility test and

variance ratio test have been used to test randomness of world markets.
