Overview Mitani and co-authors’ present a deep-learning algorithm trained with retinal images and participants’ clinical data from the UK Biobank to estimate blood-haemoglobin levels and predict the presence or absence of anaemia (Mitani et al.

## Approximating Binomial with Poisson

It is usually taught in statistics classes that Binomial probabilities can be approximated by Poisson probabilities, which are generally easier to calculate. This approximation is valid “when $$n$$ is large and $$np$$ is small,” and rules of thumb are sometimes given.

## Importing Flat Files Into R
