[Gretl-users] Re: cross-sectional panel data

Thanks, Allin, Really what I want is to convert wide data to long. Which SPSS can do. As I don't want to teach the students two packages, I think I will teach them how to manipulate the data in excel first and then read it in.

The method discussed in the manual is designed to handle a somewhat simpler case, where the organization of the original source data is closer to, though not equal to, what gretl wants. Frankly, the format you're talking about is pretty weird and I'd be surprised if any econometric software could make sense of it without a good deal of work. In case there's any doubt, what gretl wants from a panel dataset is a column for each variable and a block of T rows, in temporal order, for each of the N units or "individuals". Considered as a matrix it will be NT x v, where v is the number of variables. This is the "natural" generalization of cross-sectional data (N x v) and time-series data (T x v).
