I) "Data" menu: I interpret that as relating to the loaded
dataset as a whole, so one may think of
renaming that to "Dataset" instead. Given that interpretation, the following
items should be moved
elsewhere:
1. graph specified vars (-> "sample")
2. Multiple scatterplots (-> "sample")
3. everything from summary statistics to differences of variances should also go to
"sample"
II) "Sample" menu: in my view, all commands that act on or modify data in the
current sample range
(as opposed to the entire dataset) should come here. (see what was moved from
"data" in I) Therefore
remove:
1. Dataset structure / compact data /expand data (-> "data(set)")
2. restructure panel / transpose data (also -> "data(set)")
[3. not sure about the missing-value and case marker things, don't know enough about
them)
III) "Variable" menu: interpreted as variants of univariate analsis, so move:
1. find (-> "data(set)")
2. define new variable ( "data(set)")
[3. again not sure about the missing-value issue, why here _and_ in "sample"?)
So what do you guys think? Of course experienced users would have to adapt, but I would
argue the
changes are relatively mild and make more sense in the longer run.
Makes sense to me, although the distinction you draw between "data" and
"sample" looks a bit fuzzy to me: following your logic, the whole
variable-generation machine should go under "sample".
And while we're at it, is the model menu to be left untouched? I mean, I
wouldn't mind an organisation like
OLS
-------------
Other least-squares estimators -> IV, Weighted, ...
-------------
Time series
-------------
Qualitative & limited dependent -> Logit, Probit, Tobit
-------------
Count data -> Only Poisson for now
-------------
System -> VARs could go in here
-------------
Other
