How to remove the testing bias in CoV-2 statistics	2020-10-16		.txt	text/plain	7041	518	63	Private and public decision making should not be based on time series of CoV-2-infections as the latter do not provide information about the true epidemic dynamics in a country. 3 We show that time series on the number of tests and time series on reported infections do not allow one to obtain information about the true state of an epidemic. It also studies the (lack of) informational content of time series on reported infections and time series on the number of tests, and the properties of the positive rate. Testing increases the positive rate if the number of tests undertaken due to symptoms 17 This paper is about conceptional issues related to the …nding an unbiased estimator for an unobserved time series. If we knew the number of Covid-19 cases, i.e. CoV-2 infections with severe acute respiratory symptoms (SARS), then we would know at least one part of epidemic dynamics (Ĩ symp (t) in our model).	./cache/cord-334274-4jee19hx.txt	./txt/cord-334274-4jee19hx.txt
