During the day, I forecast sales at supermarkets, drugstores, furniture, perfume and other retailers and calculate order proposals. Lots of time series, with an emphasis on fast, automatic and robust data cleansing and forecasting - with some logistical optimization thrown in for good measure. I'm active in the International Institute of Forecasters and an Associate Editor for their practitioner-oriented journal Foresight.

At night, I switch hats and do inferential statistics for clinical and biological psychology.

I'm never bored. And I use R.

comment efficient way to invert a Matrix plus a diagonal one
Thx. That could have an impact on possible approaches, so I took the liberty of editing your question to include this info. I'll delete my comment and suggest you do so, too, to clean up.
