Hi everyone, I have this kind of raw dataset : - <Temp diffgr:id="Temp14" msdata:rowOrder="13"> <Date>2005-01-17T00:00:00+05:30</Date> <SecurityID>10149</SecurityID> <PriceClose>1288.40002</PriceClose> </Temp> - <Temp diffgr:id="Temp15" msdata:rowOrder="14">

hi, I considered multivariate multiple regression for respons, predictor, each 5 dimension. on going process, through initb <- eigen(temp)$vectors[,1:3] temp <- vhalf%*%Kproduct(Ir,initb) (herein 'vhalf' is root for inverse of covariance matrix and 'Kproduct' is Kronecker product) and then process regression. However, I have tried using the

Hello and thanks in advance to those who post back, I''m working on a calender but, it renders the data in the controller then saves it as @code so I call it in the veiw <%= @code %>. So everythings working and I add this line.. @event = Event.find_by_date("#{@temp13.year}-#{@temp13.month}-#{@temp13.day}") if @event == nil @@td = "<td width=50 height=50

Hi everyone and Achim, Achim, I appreciate your help about the function "NCOL". When I use "NCOL" instead of "ncol", I can find out the number of columns (number of time series) in the presence of only one time series (one variable, one column). Now I want to know how I can find out the column names of the zoo objects? In case of more than one time series, the

Hi, Part of my program is to calculate the number of time series in a zoo object. It works well if it has more than one time series, but it fails if it has only one. How can I access the number of column (i.e. the number of time series) when I have only one column? Why is the number of an object of only one object "NULL"? It should be one, shouldn't it? (The following example
