In this paper, to avoid confusing that term with the more familiar statistical variance, which might apply to the whole distribution, we term it "within-side variance".
From surgical experience the author is familiar with variance in only the height of implants, with lateral and AP dimensions remain largely uniform within company models.
We do not offer a proof of Eq. (9), but readers familiar with the variance of a product of two independent random variables (i.e., var(WZ) = E(W 2 var(Z) + E(Z 2 var(W) + var(W var(Z)) can identify the similarity with Eq. (9).
Some familiar results relating sample variance to sample size are shown to be special cases of the more general result.
The solution for the exemplary matrix of response latencies presented above is shown in Fig. 2. Since on average already the first dimension accounted for 87.4% and 89.0% of the variance for familiar and unfamiliar motifs, respectively, we obtained only one-dimensional solutions of the Proxscal algorithm and used these data to calculate the perceptual distances.
Thus, this approach to the estimation of C avoids the biases inherent in constraining C > 0 in the more familiar ML components of variance approach.
Mean parameter estimates for each region were entered into separate 2 × 2 × 2 analyses of variance (ANOVAs) including Familiarity (familiar, unfamiliar), Size (same-size, vary-size), and Repetition (same-identity, different-identity) as repeated measures factors.
These diverging results may be due to more variance in how familiar preschool teachers and caregivers are with the children in the US compared to in Norway.
Practitioners are likely to be familiar with the concept of zero variance, but are perhaps less likely to appreciate why a correlation is estimated at unity.
