It details how many predictions are true and how many are false.The report presents the main classification metrics—precision, recall, and F1-score—for each class. These metrics are calculated using true and false positives, along with true and falsenegatives.
I did aclearblue pregnancy testwhen i was 4 days late and it showed up with a very faint blue line. I had to hold it up to the light to see the result.If you do have a low level of the pregnancy hormones, that would explain why the line was just faint. I agree - go for another test.
