Uncertainty in a financial model
#First we are going to set up probability distributions for our beliefs about the inputs
#We've been told ARPU is about £7 and it's very unlikely to be higher than £10 or lower than £4
#So we'll go for a normal distribution centred at 7 with 5% and 95% quantiles at 4 and 10
#Show how we get the variance

Uploading to S3 in 18 lines of Shell (used to upload builds for http://soltrader.net)
# You don't need Fog in Ruby or some other library to upload to S3 -- shell works perfectly fine

IronistM / sql.export.randomForest.R
Created May 24, 2017 12:56 — forked from shanebutler/sql.export.randomForest.R
Deploy your RandomForest models in SQL! This tool enables in-database scoring of Random Forest models built using R. To use it, you simply call the function with the Random Forest model, output filename, SQL input data table and the name of the unique key on that table. For example:sql.export.rf(rf.mdl, file="model_output.SQL", input.table="sour…

IronistM / upgrade_packages.R
Created September 26, 2017 06:57 — forked from bearloga/upgrade_packages.R
The script can be used to re-install packages after upgrading R (on Linux or Mac), since libraries cannot be reused between different minor versions (e.g. when upgrading 3.2.3 to 3.3.2). It detects when a package was installed from CRAN vs GitHub/Git and re-installs it using the appropriate func. Usage: `Rscript upgrade_packages.R`
# WMF only:
if (file.exists("/etc/wikimedia-cluster")) {
message('Detected that this script is being run on a WMF machine ("', Sys.info()["nodename"], '"). Setting proxies...')
Sys.setenv("http_proxy" = "http://webproxy.eqiad.wmnet:8080")
Sys.setenv("https_proxy" = "http://webproxy.eqiad.wmnet:8080")
