We also calculated the coefficient of variance among the soil samples.
The software calculated the coefficient of determination as percentage, slope of the linear trend model with direction of the trend.
Considering the differences between the compared data sets, we calculated the coefficient of repeatability as 2 × standard deviation.
We also calculated the coefficient of variation in the diameters, a measure of polydispersity, and included this is Table 1.
We built a linear regression model and calculated the coefficient of determination R 2 to measure the strength of association between all possible permutations of variables.
We developed a regression formula for calculating ID and OD based on age in months and calculated the coefficient of determination R2 by using a regression analyses.
To evaluate the performance of each method, the following statistical indicators are calculated: the coefficient of determination (R 2), Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), Mean Absolute Relative Error (MARE) and average absolute deviation.
We calculated the coefficient of variation (CV) to assess reproducibility.
To compare predictions with measurements, we calculated the coefficient of determination, R2, between the predicted and observed PSA values.
Further, for all extracted parameters we calculated the coefficient of variation (CV), which is a normalized measure of the dispersion of a probability distribution.
We calculated the coefficient of variation (CV) of the three sample dates' values for DEA, mass-standardized DEA, and the soil variables to quantify variability through time.
