As shown in Figure 7, the instability index increased over time only when the cells stopped cycling (+0.09 instability index units/week, linear regression model: Instability index ~Weeks, p value, 0.0015), but not when cells continuously proliferated (+5 × 10-5 indexbility index units/week), consistent with the prediction from the negative correlation between cell cycle and the instability index.
Through linear regression of refractive index against concentration, the specific refractive index increment α for protein at 310 nm is determined to be 0.208 ± 0.001 mL/g, which is slightly lower than that measured using the light scattering method.
a, Drought sensitivity as the slope in an ordinary least-squares linear regression of an index of the variation in aboveground plant water content at midday compared to night (regression: VODmidday = β × VODnight + ε).
Transaction data, Market Model coefficients and, estimated through linear regression and General Index (GI) data were then combined to form the final dataset of the Data Selection process.
Combining unigrams and bigrams through a multiple linear regression model, the index was 83.95 % and that of the human evaluators was 84.93 %.
Cerebral autoregulation was assessed by Pearson linear regression coefficient (Mx index) between MCA FV and MAP during spontaneous fluctuations of MAP (cut-off of Mx ≥ 0.2 was adopted to define impaired autoregulation).
The threshold r value 0.80 (for hESCs) or 0.90 (for mESCs) that we chose corresponded to the linear regression model fitting index R2 value 0.84 or above, which suggests scale-free topology of the resulting network.
The linear regression model fitting index R^2 can be used to quantify how well a network satisfies a scale-free topology.
Individual DLCO, DLNO, and VC measurements were analyzed with respect to Q̇; slope of the linear regression provides an index of alveolar-capillary recruitment (7).
Beta was chosen based on the scale-free topology criterion [ 10] whereby the linear regression model fitting index (R) was used to quantify how well the network satisfied this criterion.
