Calculation of RMSE, MAPE, correlation coefficient R. Evaluation of achieved results.
A warning of the dangers of using correlation coefficients in evaluation of diagnostic tests is included in the QAREL [ 4] guidelines but not in STARD or QUADAS [ 5, 6].
We adopt the correlation coefficient as the evaluation indicator to identify the relationship between the south north Z rate differences and Z rates of a designated area in Rule 1.
[left] The Pearson correlation coefficient ρ α,β evaluation of the measured Φ α. [right] The ecdf curves of (Phi _{n}^{alpha }).
Spearman's rank correlation coefficient was used for evaluation of correlations.
The intraclass correlation coefficient (ICC) for ADC evaluation between the two readers was 0.852 955% CI 0.661 0.935; P = 0.0001).
For the quantification of the reproducibility, three types of analysis were applied: Cohen's kappa statistics and the Bland and Altman method for assessing agreement and the Intraclass Correlation Coefficient (ICC) for the evaluation of reliability.
Four different evaluation measures have been calculated for assessing performance of stated strategies: accuracy, specificity, sensitivity and Matthew's correlation coefficient (MCC) (see the Performance evaluation subsection in the Methods section).
'Correlation coefficient is a generally used evaluation to establish the relationship between two variables.
The experimental results showed that the Pearson correlation coefficient between the system's evaluation outcomes and the traditional Montreal Cognitive Assessment scores was 0.83.
