How can they predict the shape of the bell?
(distribution of the possible numbers of infections over the days)
During this corona virus I have seen many pics of normal distributions which should predict the number of the infections over the days.
As predictive model I only know the regression.
My question is:WHere do These distribution predicting the number of infections of corona virus over the day come from?
Are they calculated based on a previous regression made or do they use another kind of model to compute them?I have seen that they also have confidence intervals all over the line that draws the ''bell shape'' as if it was a regression line.. but it was a distributionCan someone explain to this statistic ignorant?
