To understand the selection mechanism behind mutations, network - based studies were used to estimate the importance of a mutated protein compared to non-mutated ones in signalling and protein — protein interaction networks.10, 11,12,13 Proteins mutated in cancer were found having a high number of interacting partners (i.e., a high degree of connectivity), which indicates high local importance.10 Mutated proteins are also often found in the centre of the network, in key global positions, as quantified by the number of shortest paths passing through them if all proteins are connected with each other (i.e., they have high betweenness centrality; hereafter called betweenness).11, 12 Mutated proteins also have high clustering coefficients, which means their neighbours are also neighbours of each other.10, 13 Moreover, neighbourhood analysis of mutated proteins have been previously successfully used to predict novel cancer - related genes.14, 15 However, to the best of our knowledge, no study has concentrated particularly on the topological importance of first neighbours of mutated proteins in cancer, and their usefulness as drug targets themselves.

When assessing maximal knee angle (flexion), mean power output in the concentric phase a squat exercise, and vastus lateralis EMG amplitude, the test - re-test reliability measured by the coefficient of variation (COV) ranged between 5.3 — 7.8 %, which suggests that these measurements are comparatively consistent but not perfectly replicable.

To complete the task cards students will use knowledge of linear regressions (line of best fit, least squares regression), correlation coefficients, and calculating residuals and their meaning.

In Dallas, Fort Worth, and Houston, the coefficients of variation were nearly always more than 0.15, meaning that one - third of the schools in these districts had spending levels that deviated from their district's average by 15 percent (or $ 225,000 for a school of 500 when average spending is $ 3,000 per pupil).

Since the mean value of our two spending indexes is 1.0, the coefficient of variation is actually equivalent to the standard deviation in our analysis.

We define the coefficient of variation as the standard deviation of the population divided by its mean.

These coefficients differ from the mean special education rates in Figure 1 because they refer to differences from the mean for whites, the excluded group in the regressions.

If a state with a 0.17 coefficient spent $ 13,000 per pupil, the average variance among district spending within the state would range from $ 11,310 to $ 14,690 per pupil ($ 1,690 above or below the mean of $ 13,000).

Then, θ gives the coefficients in the (weighted) minimum mean - square - error linear predictor An alternative could use the absolute value of the error instead of the squared error in Eq.
