Hello.(adsbygoogle = window.adsbygoogle || []).push({});

I developed an algorithm to detect events in time domain and I want to know the efficiency of the algorithm.

The problem is related with the time duration of the data.

Each file has data with a time duration of hundreds of minutes and I have dozens of files.

Instead of calculate the specificity and the sensitivity of this algorithm for the entire data set, I was thinking to choose random samples.

My question is:

What is the correct approach to have a valid statistical analysis?

Thank you.
