Hi: Works for me:
> library(tseries) Loading required package: quadprog Loading required package: zoo ‘tseries’ version: 0.10-25 ‘tseries’ is a package for time series analysis and computational finance. See ‘library(help="tseries")’ for details. > x<- as.ts(rnorm(1000)) > str(x) Time-Series [1:1000] from 1 to 1000: -2.221 0.183 0.381 -0.263 0.19 ... > terasvirta.test(x) Teraesvirta Neural Network Test data: x X-squared = 0.8622, df = 2, p-value = 0.6498 Did you load the tseries package before trying to call the function? If so, perhaps you need to upgrade your R version and/or your version of the tseries package. > sessionInfo() R version 2.13.1 (2011-07-08) Platform: x86_64-pc-mingw32/x64 (64-bit) locale: [1] LC_COLLATE=English_United States.1252 [2] LC_CTYPE=English_United States.1252 [3] LC_MONETARY=English_United States.1252 [4] LC_NUMERIC=C [5] LC_TIME=English_United States.1252 attached base packages: [1] stats graphics grDevices utils datasets grid methods [8] base other attached packages: [1] tseries_0.10-25 zoo_1.6-5 quadprog_1.5-4 ismev_1.36 [5] sos_1.3-1 brew_1.0-6 lattice_0.19-30 ggplot2_0.8.9 [9] proto_0.3-9.2 reshape_0.8.4 plyr_1.5.2 loaded via a namespace (and not attached): [1] tools_2.13.1 Dennis On Sun, Jul 10, 2011 at 3:17 PM, Aravind R.N <aravin...@gmail.com> wrote: > Hi, > > I tried running the function terasvirta.test in the package tseries > for a univariate tseries object. > > For eg. > > x<- as.ts(rnorm(1000)) > terasvirta.test(x) > > I get the following error > Error in as.matrix(y) : argument "y" is missing, with no default > > The function seems to expect a default y argument for regressing.
