Re: [STARS] a quick question about data used in STARS

[Young K. <wis...@ya...>]

Hello Mark

Just a quick correction for your posting:
FAQ is not there in STARS webpage yet, so Ling might
not be able to find any info on this problem in FAQ.
;-)

Thanks !

Young

Unfortunately, STARS currently has no method for ignoring a
cross-section in a project.  You have a couple of avenues for your
project:

1.  Consolidate or estimate the values for the missing cross-section.  You
could use the mean of GDP for all the regions or perhaps the spatial
lag.

2.  You could eliminate the cross-section in ArcView.  I cant recall the
steps involved, but it isnt very difficult to eliminate a shape from a
shapefile in ArcView.  Check the help menu.


This is a very good question and is also mentioned in the FAQ.  We will
look to remedy this situation in the future.  I hope all works out well.
Please reply when you get it figured out.  Im sure others will run into
the same problem.

Best wishes,

MJ

[STARS] a quick question about data used in STARS

[<ld...@gm...>]

Hi, there,
I am trying to use "Merge ASCII Data" menu to merge ".csv" file to the existing STARS project. But I don't know what should I do for those missing values. I know for SAS data file, ".." is used. But what should be used in STARS?  
For example, if there are 30 regions in the map, but I only have GDP per capita data for 29 regions. How should I cope with those missing values? I've tries "..", ".", and some others and they don't work. 
Thanks.

[STARS] ANN: STARS Version 0.7.2a (Linux and Mac OS X)

[Serge R. <se...@ro...>]

This is a bug fix release which affects only the Linux and Mac OS X
versions. As the Windows binary and source files for 0.7.2 were released
after the bugs were detected and fixed, users of those versions need not
upgrade.

These bugs only affected the original ProjectMaker.py file and the
associated example data for California.



Change log:

0.7.2a 2004/7/12

- ProjectMaker transpose bug fixed (mvj)
- ProjectMaker example data corrected (mvj)
- Typo in ja's name in credits (sjr)

Note: first two bugs only affect the Linux and Mac OS X
releases in 0.7.2 - the windows zip file and binary were
made with the fixes for first two bugs. Third one will remain till
next bug-fix release

0.7.2 2004/7/09
Initial public end user release

[STARS] STARS 0.7.2 Released

[Serge R. <se...@ro...>]

STARS: Space Time Analysis of Regional Systems
Version 0.7.2
Released 2004-July-09

STARS is an exploratory data analysis package designed for variables measur=
ed for
geographical units over time. It combines a series of statistical graphics =
and
mapping views together with some newly developed measures for space-time
statistical analysis. The views support several types of dynamic
visualization:

    - Linking different views to examine a given observation across differe=
nt
      dimensions (spatial, temporal, distributional)
    - Conditioning (brushing) one or more destination views on the selectio=
n of
      a set of observations on an origin view
    - Animations of of maps, distributions, box plots, scatter plots, paral=
lel
      coordinate plots and other views over time
    - Spatial traveling
    - Roaming windows
    - View generated views (creating new views from existing views)

STARS includes a suite of computational modules:
    - Classic descriptive statistics
    - Exploratory Spatial Data Analysis (Local and Global Spatial
      Autocorrelation)
    - Inequality Analysis
    - Distributional mixing and mobility
    - Classic Markov and Spatial Markov methods

STARS also includes utility methods for creating different types of
geographical weight matrices, variable transformations, and for reading
ArcView shapefiles to develop STARS projects.

STARS is written in Python, making heavy use of Numpy and Tkinter, and is
released under the GPL. =20

Source tarballs, a Windows binary installer, as well as user guides,
QuickTime tutorials, background papers and other documentation can be found=

the project's homepage: http://stars-py.sf.net
