This week's #TidyTuesday is about federal spending. I was interested in understanding if spending had shifted towards clean energy sub-agencies in the last 20 years.

The principle of the solution is that converting each currency can be done in parallel using the map function while the consolidation of the results will be done using the reduce logic.

Generate scenarios correlated to existing ones

In quantitative finance we often look at simulations of some market risk factors like equity returns or interest rate changes. There are many third party companies who specialize in the historical calibration of such variables and provide simulations of future expected outcomes to the companies who require them. For example, let’s suppose that we receive the expected returns of the Google shares as per the following distribution # This modelling is given by the third party and in theory we don't know it google <- rnorm(10000, mean = 0.
