Dear John,
Without investigating your data and models in detail, it's not
surprising that the p-values for the two coefficients differ: the models
have different residual standard errors (and hence different coefficient
standard errors) and different residual degrees of freedom (and hence
are
The question that follows in NOT an R question, but rather a statistics
question. I hope you will forgive my statistics question.
I am investigating interrupted time-series analysis. My data has two periods,
period 0 and period 1. In period 0 the slope is positive. In period 2 the slope
is nega
I understand. Thanks. My NA rows are to follow the end of the shorter matrix,
to make the two matrices same depth (number of rows), as in Garbor’s
demonstration:
[,1] [,2] [,3] [,4]
[1,]1759
[2,]286 10
[3,]397 11
[4,]4 108 12

You don't have to arrange that the shorter one comes second. The
cbind.ts approach works whether the shorter one is first or second.

Thanks to all. In my application I can always arrange to have the shorter
matrix come second which is to be filled with NA. I Will try the ts approach.
Words work less effectively for me. This could have work if plain R can be more
accommodating in cbind. Thanks.

This capability that ts objects have seems ill-advised. There is always a
meaning associated with which row and column a matrix has, and this assumes
that the shorter dimension is associated with times corresponding to the first
rows of the longer matrix. In general you don't know whether the NA

conference with this printed on the back. Vaguely recall having the code, but I
can't
find it now.

cbind does work on differently shaped ts objects so:
a <- matrix(1:12,nrow=6)
b <- matrix(5:12,nrow=4)
tmp <- cbind(ts(a), ts(b))
array(tmp, dim(tmp))
giving

Not an expert, but from my read of the explanation you linked, the .svg
IS the source. You could think of it as the source for .svg render engines,
