Re: [R] Simultaneous estimation of mean and garch eq'n

It is my experience that location parameters are not very affected by the garch parameters. So doing a naive estimate of location, followed by the garch estimate, followed by an estimate of location accounting for heteroskedasticity is likely to be indistinguishable from the estimates from the ful

[R] attached file with syntax error

oops, I forgot to attach the example txt file with the syntax error, so I will do it here, can anyone see what the error is with bryansAtLineLevel? bryansAtHeaderLevel <- c(0,1,1,1,1,0,0,0,0,0,0,1,0,0,1,1,1,0,0,0,1,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,0,0,1,0,0,1,0,1,0,1,1,1,

[R] Why does this give a syntax error?

Hi I'm generating the following in a file and getting a syntax error: bryansAtHeaderLevel <- c(0,1,1,1,1,0,0,0,0,0,0,1,0,0,1,1,1,0,0,0,1,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,0,0,1,0,0,1,0,1,0,1,1,1,1,1,1,0,0,1,1,1,0,0,1,1,0,0,1,1,1,1,1,1,1,1,1,0,0,1,0,1,0,1,1,1,1,1,1,1,1,1,1,0,

Re[2]: [R] Lattice: how to get default ylim?

Thank all very much for answers. grid.text in the Deepayan's varian did the trick satisfactory. However, at any rate it would be great to have access to the information about viewports, because I would like text not to overlap the graphics. Therefore its placement should be calculated with respect

Re: [R] Simultaneous estimation of mean and garch eq'n

This might be one of those situations in which you should say what what you are trying to do rather than how you are trying to do it. It is my understanding that estimates of b are asymptotically well behaved in this situation, at least for b<1. If, however, you are trying to get CI's for b in fi
