Sentence examples for unstable variance from inspiring English sources

This may result in unstable variance (noise) estimation [ 26].

The regression coefficient was loge-transformed to account for non-normality and unstable variance.

The shrinkage estimator (5) avoids unstable variance estimates when the available degrees of freedom v=∑ g (K g −1) are small.

Shown are the significance level (P-value) and F-value of each model term; the regression coefficient was loge-transformed to account for non-normality and unstable variance; † n.t.

Each method used a slightly different strategy to estimate a penalty parameter for smoothing unstable variance estimates, using information from all genes rather than relying solely on variance estimates from an individual gene.

All of these methods focus on overcoming the shortcoming of the ordinary t-statistics for ranking genes, due to unstable variance estimates that may arise when sample size is small.

The issue of multicollinearity is currently ignored in the ADP literature, but in the statistics community it is well known that high multicollinearity leads to unstable (high variance) parameter estimates in statistical modeling.

The correlation between the ipsi- and contralateral finger patterns was calculated as: (2) Because these correlation estimates could become unstable if the variance associated with the finger patterns was very low, a very small constant (1e−5) was added to all finger variances.

When r is large, the estimator of variance is unstable.

Because of the potential for strong multicollinearity among the 24 monthly climatic anomaly variables, standard regression techniques are likely to yield inflated parameter variances and unstable parameter estimates.

This means that memetic with crossover may cause large variance and increase unstable factor of PSO algorithm; however, the results becomes more stable with parameter adaptive method.
