How can I plot the confidence intervals from the fitlme mixed model?
lme = fitlme(T1,' par ~ 1 + cov + (1 I ID)','FitMethod','REML');
Example:
Image 8.jpg
Results:
Fixed effects coefficients (95% CIs):
Name Estimate SE tStat DF pValue Lower Upper
{'(Intercept)'} 0.021452 0.0022428 9.5647 50 7.0315e-13 0.016947 0.025957
{'cov' } 0.00022556 0.00017193 1.3119 50 0.19554 -0.00011977 0.0005709

The plot image is only showing for standard regression not included random for the intercept in this case. The lme. Coefficient is only one value and it is not calculated over the prediction line.

If you look at the linear mixed model documentation you should be able to extract the confidence interval values from lme.Coefficients.Upper and lme.Coefficients.Lower. (They are the red dotted lines already in your plot, by the way).
