Hello, attached is a gzipped patch file to the lib/mcomp.c source file of theora (as of AnonCVS current version) that implements MMX and extended-MMX optimizations in the most frequently used functions of the encoder (as shown by gprof). This is more a proof of concept than a real request for inclusion into the source tree. My personal intent was more t...

Hey, I am using the ets() function in the forecast package to find out the best fit parameters for my time-series. I have about 50 sets of time series data. I'm currently using the function as follows: ets(x,model="AZZ",opt.crit="mse") As to my observation about 5-10 of them have been identified by ets to have a trend and an alpha, beta values have been thrown up -

Is it not possbile to get adjusted p-values after
