I want to include the errorbar on my F1 score plot. I don't know how to go about it. Here is my code below

% Given data

p = [3, 4, 5, 6, 7, 8, 9, 10, 11, 12];

TPR_PCA = [79.4, 80.25, 83, 90.50, 91.31, 91.34, 91.34, 91.35, 91.35, 91.35] / 100;

TPR_kPCA = [80.50, 81.70, 85.85, 92.25, 92.40, 92.45, 92.44, 92.48, 92.50, 92.50] / 100;

PREC_PCA = [71.05, 72.50, 76.70, 86.00, 86.20, 86.20, 86.25, 86.27, 86.27, 86.28] / 100;

PREC_kPCA = [72.20, 73.00, 78.95, 88.40, 88.56, 88.56, 88.56, 88.56, 88.56, 88.56] / 100;

% Compute F1 scores for PCA-HMM and kPCA-HMM

F1_PCA = 2 * (TPR_PCA .* PREC_PCA) ./ (TPR_PCA + PREC_PCA);

F1_kPCA = 2 * (TPR_kPCA .* PREC_kPCA) ./ (TPR_kPCA + PREC_kPCA);

figure;

subplot(1,2,1) %SRW

plot(p, F1_PCA, 'kx-', 'MarkerSize', 8, 'DisplayName', 'SRW:PCA-HMM');

hold on;

plot(p, F1_kPCA, 'mo-', 'MarkerSize', 5, 'DisplayName', 'SRW:kPCA-HMM');

hold off;

xlabel('p');

ylabel('F1 Score');

title('\textbf{(a) F1 score @ $\mathcal{W}$=128}', 'Interpreter','latex');

legend('Location', 'southeast');

grid minor;

Use errorbar -

% Given data

p = [3, 4, 5, 6, 7, 8, 9, 10, 11, 12];

TPR_PCA = [79.4, 80.25, 83, 90.50, 91.31, 91.34, 91.34, 91.35, 91.35, 91.35] / 100;

TPR_kPCA = [80.50, 81.70, 85.85, 92.25, 92.40, 92.45, 92.44, 92.48, 92.50, 92.50] / 100;

PREC_PCA = [71.05, 72.50, 76.70, 86.00, 86.20, 86.20, 86.25, 86.27, 86.27, 86.28] / 100;

PREC_kPCA = [72.20, 73.00, 78.95, 88.40, 88.56, 88.56, 88.56, 88.56, 88.56, 88.56] / 100;

% Compute F1 scores for PCA-HMM and kPCA-HMM

F1_PCA = 2 * (TPR_PCA .* PREC_PCA) ./ (TPR_PCA + PREC_PCA);

F1_kPCA = 2 * (TPR_kPCA .* PREC_kPCA) ./ (TPR_kPCA + PREC_kPCA);

%Size of the error bar you want

err = 0.005*ones(size(p));

figure;

errorbar(p, F1_PCA, err, 'kx-', 'MarkerSize', 8, 'DisplayName', 'SRW:PCA-HMM');

hold on;

errorbar(p, F1_kPCA, err, 'mo-', 'MarkerSize', 5, 'DisplayName', 'SRW:kPCA-HMM');

hold off;

xlabel('p');

ylabel('F1 Score');

title('\textbf{(a) F1 score @ $\mathcal{W}$=128}', 'Interpreter','latex');

legend('Location', 'southeast');

grid minor;

xlim([2 13])

I don't understand.

Could you please show an example or specify more about what you want to obtain?

Thank you again @Dyuman Joshi

I have developed two models, PCA-HMM and kPCA-HMM. I have computed the F1 score for the two models on the same plot. Now, I want to use the error bar to evaluate conficen interval (or assess the level of confidence) in my results and how the error bars can be used to gain more insight about the results.
