Survival Analysis #3

Open alainapb opened 3 years ago

alainapb commented 3 years ago

Right now the analyses are calculating death post-exposure, so shouldn't controls be exclude (because they were not exposed)?

Or we can run a more general survival analysis

Great question! Technically, we should be doing a sham exposure...with heat-killed spores etc. but I've never figured out a good way to do this. As far as I can tell, none of the Daphnia experiments do this, so it's not best practice in science, but it's just an excepted 'issue'. So given that, the survival analysis only make sense if we compare survival of infected vs. uninfected...and we aren't interested in their survival before the experimental treatment so that's why it's 'post-exposure does that make sense?
