Hi Victor,
I understand that you want to generate Bayesian information criterion values for a given excel file and further plot them with number of components.
Please follow the below steps to do so:
1. Import the file to a table ‘T’ using the “readtable” function.
T = readtable('fileName.xlsx');
2. Calculate the BIC of each estimated model using “aicbic” function. Specify the sample size ‘numObs’, which is required for computing the BIC.
[~,bic] = aicbic(logL,numParam,numObs)
You can refer to the below documentation to know more about the “aicbic” function:
3. Plot the BIC and number of components, you can use the “bar” function to plot them as bar chart.
bar(bic,numComponents)
MATLAB offers various functions for plotting data, you may explore other options
I hope this helps!
Regards,
Karanjot Singh
