In the general case, I suppose, one could always order the data frame by
date before proceeding ?
Thanks,

Hi,
I have a dataframe, x of the following form:
DateSymbol AB C
20041201 ABC 10 12 15
20041201 DEF 95 4
...
20050101 ABC 5 3 1
20050101 GHM 12 42
here A, B,C are properties of a set symbols recorded for a given
Hi,
I have a data set with a continuous predictor X, a factor A and a continuous
dependent
variable Y.
I am trying to build a linear model of the form:
Y = (b0 + b1*X1)*B(A)
where B(A) is a constant for each level of the factor A.
I am not quite sure how to formulate the appropriate model
Hi,
I have the following problem which I would appreciate some help on.
A variable y is to be modelled as a function of a set of variables
Vector(x).

property that y(i) = z(i).
So the data set is divided into three
