Hi,
I understand that you would like to calculate the p-value for 'R2' based on the provided code. To calculate the p-value for ‘R2’ in MATLAB, you can use utilize the following code:
df_regression = 1; % Linear model.
df_residual = length(Wsim(:)) - 2; % N - 2 degrees of freedom for residuals
F_statistic = (R(nok) / df_regression) / ((1 - R(nok)) / df_residual);
p_value = 1 - fcdf(F_statistic, df_regression, df_residual);
To learn more about “fcdf” usage and syntax, you may refer to the MathWorks documentation link below:
I hope this helps!
