[R] Converting the results of granger.test into a matrix

Dear R Users, The granger.test command in the MSBVAR package estimates all possible bivariate Granger causality tests for m variables. If one passes a data frame with 3 rows, it returns 6 granger tests in two rows, one for the F-statistic and another for the p-value. For example:

[R] Regresions based on Empirical transformations and varying distributions

Dear R-users, This is partially a R question and partially general econometrics. I have three time series which are somewhat dissimilar: plotting their histograms indicates that they do not come from the same distribution, never mind a normal distribution. I wish to predict the first as a

[R] Replacing values in a zoo object

Dear R Users, I am trying to replace the value of one row in a single column zoo object. I try the following, but it does not seem to work. Could someone explain to me how I can either replace the value for this row or just delete the row entirely ? Many thanks in advance, Tolga

[R] Problems with Cochrane-Orcutt procedures

Hi John, Hi Folks/Prof. Fox, I found some code John Fox had written sometime back on the Cochrane-Orcutt and Prais procedures here: https://stat.ethz.ch/pipermail/r-help/2002-January/017774.html I thought I would try it out and get the following errors below. Was wondering if anyone had any

Re: [R] Problems with Cochrane-Orcutt procedures

Sure, I can imagine GLS is a much better way to deal with this. I guess I was looking at this because I did try GLS but got exactly the same results as LM and I just wanted to be sure. I did debug the code in https://stat.ethz.ch/pipermail/r-help/2002-January/017774.html and the offending

Re: [R] Problems with Cochrane-Orcutt procedures

Aha ! I think this is it. You are using a data frame, and I was using zoo for the regrCMS object. When I cast it into a data frame, it then works ! I guess it would be cool to understand why it doesn't work as a zoo object, but no matter. Thanks John, Tolga regrCMS-as.data.frame(regrCMS)

[R] col.names ?

Dear R Users, A bit of an elementary question, but somehow, I haven't been able to figure it out. I'd like to changes the column names of a data frame, so I am looking for something like col.names (as in row.names). Could someone please show me how to change the column names of a data frame ?
