Detected or not detected as outcome for response variable - which type of logistic regression analysis?

[Biochemist]

Hi,

If I have a response variable with detected or not detected (= factor below detection level or above detection level / present or not present) as the outcome, then which logistic regression analysis would I have to use: simple binary logistic regression or ordinal logistic regression?

I mean, after all, detected (present) is more/higher than not detected (not present). Or does it only matter that the outcome is binary here?

i think binary is what you want.

Alright, thank you. Then, I will use binary logistic regression in this relatively simple case.
