Array as time series?
Dear R-helpers,
I have 4-dimensional atmospheric data (x,y,z,t), which I want to analyse
on spatio-temporal diversities.
As far as I understand there only exists the possibility to construct
time series as two-dimensional matrices (mts).
For the moment, I hold it in different objects:
1. a four-dimensional array for the spatial related analyses
2. a two-dimensional mts timeserie, which was

measurement error model - "simple" linear regression
Dear friends, I found the thread on this subject this summer but
wonder whether it has been taken any further. I have an important
medical problem where X is computed from a three independent and
complicated measurements (exchangeable sodium and potassium and total
body water - i.e. X = (Nae+Ke)/TBW ) and Y is serum sodium
concentration (all data in Edelman, JCI 1958). I have the individual

Offline change detection methods?
Dear [R] people, I am looking for a method to test if there are any
changes (jump points) in a time series data set or not. If there are, I
would like to identify the jump points. All the data is available from the
beginning so an offline method could be used.
The current data set that I have could be seen as a time series with
five almost equally sized segments that stands out to have different
