Dear R users, I am trying to use tseries' garch function in order to determine the volatility of a return series generated by quantmod. Here is the code that I am using: > library(quantmod) > getSymbols("AAPL") convert daily closing prices into continuous log returns > dret<-dailyReturn(AAPL,type='log') check to see that the autocorrelations decay > acf(dret) autocorrelations seem to oscillate to zero load package tseries need for garch > library(tseries) run garch on the daily returns > garch(dret) When Garch runs there is false convergence, whic...

Hello Everyone, I just started a new job & it requires heavy use of R to analyze datasets. I have a data.table that looks like this. It is sorted by ID & Date, there are about 150 different IDs & the dataset spans 3 million rows. The main columns of concern are ID, date, and totret. What I need to do is to derive daily returns for each ID from totret, which is simply totret at time

Fix a deadlock on hybrid graphics laptops that's been present since 2013: DRM drivers poll connectors in 10 sec intervals. The poll worker is stopped on ->runtime_suspend with cancel_delayed_work_sync(). However the poll worker invokes the DRM drivers' ->detect callbacks, which call pm_runtime_get_sync(). If the poll worker starts after runtime suspend has begun,
