Estimation and Forecast of Seasonal Component
Hi list, I would like to estimate and forecast the seasonal component of a series. My model which uses daily data would be something y t = alpha + beta x SeasComp t + gamma x OtherRegressors t. One approach to this would be use quarterly dummies, another to use a sine function. The first would cause a step change when we move from a season to another; the latter impose too much regularity in

stats::decompose - Problem finding seasonal component without trend
Hi R-help, I'd like to extract the seasonal component of a short timeseries, and was hoping to use stats::decompose. I don't want to decompose the 'trend' component so I thought I should call decompose(x,filter=0). I think I've either misunderstood the filter argument or come upon a bug/feature in decompose. # EXAMPLE

strength of seasonal component
Hi All, a) Is it possible to estimate the strength of seasonality in timeseries data. Say I have monthly mean prices of an ten different assets. I decompose the data using stl() and obtain the seasonal parameter for each month. Is it possible to order the assets based on the strength of seasonality? b) which gives a better estimate on seasonality stl() or a robust linear model like

Decompose function : calculation of each component
Hello, I'd like to know how R does calculate each component in the decompose() function? More precisely, how is calculated the final trend component in this function?

package mgcv inconsistency in help files? cyclic P-spline "cs" not cyclic?
Dear all, I'm a bit stunned by the behaviour of a gam model using cyclic P-spline smoothers. I cannot provide the data, as I have about 61.000 observations from a time series. I use the following model : testgam <- gam(NO~s(x)+s(y,bs="cs")+s(DD,bs="cs")+s(TT),data=Final) The problem lies with the cyclic smoother I use for seasonal trends. The variable Final$y is a

cyclic namespace dependency detected when loading ...
Hi R users, I am developing two packages. Each package uses some functions from the other package. Now when I define these dependencies in the NAMESPACE file (via importFrom(XXXX,function1,....)), i get this error (when building one package): cyclic namespace dependency detected when loading 'XXXXXX', already loading ?YYYYYYY?, ?XXXXXXXXX? Is there any way to prevent this error?

[PATCH] One more -x to not traverse cyclic bind-mounts
This patch allows one to repeat the '-x' option a third time to stop rsync from traversing potentially cyclic bind mounts that are on the same filesystem. For example, the following scenario would cyclically traverse the bind mounts until the OS (Linux in this case) hits a maximum traversal count, thank goodness. Other OSes may traverse the bind mount indefinitely... su cd mkdir

remove RPMs with cyclic dependancies.

I thought wilcards worked, so I tried: [root at localhost program]# rpm -e openoffice* error: package openoffice* is not installed Okay, so I couldn't figure out how to remove a bunch of RPM packages at once, so I did this: [root at localhost program]# rpm -qa | grep openoffice And

Odd r-squared
Hi, I would consider the calculation of r-squared in the following to be a bug, but then, I've been wrong before. It seems that R looks to see if the model contains an intercept term, and if it does not, computes r-squared in a way I don't understand. To my mind, the following are two alternative parametrizations of the same model, and should yield the same r-squared. Any insight much

finite mixture model (2-component gaussian): plotting component gaussian components?
