Was working with Johan Giesecke and Johan Carlsson at Smittskyddsinstitutet. Obviously, I was third in "rank" among the Johans and the reference to the 16th century Swedish King Johan III was then also obvious. At one point johaniii was taken so I switched to iiijohan.

For some reason the elder daughter was nicknamed groda (frog in Swedish) when she was small. Groda dot se was taken so I registered groda dot eu instead because I for some reason wanted a website

Use continuous data. That's the lesson of the day; people are capable of dealing with it. If you give people outs to using continuous data; you make your models much less clinically useful. #medsky

Hi, can you help me? I want to develop a model that makes risk predictions.
Use logistic regression.
Can I use some more modern techniques, like AI?
Use a neural network with single non-hidden feed forward layer that outputs to a single dimension using a sigmoid activation function.
