The last post about Mayo’s Severity Principle got me thinking about that xkcd cartoon which generated so much hate-and-discontent among Frequentists. I didn’t care for it because all Frequentists can say in response is “we’re not that dumb”; ...

Christian Robert on the Jeffreys-Lindley paradox; more generally, it’s good news when philosophical arguments can be transformed into technical modeling issues

September 17, 2013
By

X writes: This paper discusses the dual interpretation of the Jeffreys– Lindley’s paradox associated with Bayesian posterior probabilities and Bayes factors, both as a differentiation between frequentist and Bayesian statistics and as a pointer to the difficulty of using improper priors while testing. We stress the considerable impact of this paradox on the foundations of […]The post Christian Robert on the Jeffreys-Lindley paradox; more generally, it’s good news when philosophical…

Forecasting with daily data

I’ve had several emails recently asking how to forecast daily data in R. Unless the time series is very long, the easiest approach is to simply set the frequency attribute to 7. y <- ts(x, frequency=7) Then any of the usual time series forecasting methods should produce reasonable forecasts. For example library(forecast) fit <- ets(y) fc <- forecast(fit) plot(fc) When the time series is long enough to take in more…
