LISA: Flag and block use of residuals #131

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
Add flag to global Moran scatterplot and LISA maps when people try to load the 
OLS residuals field, sth like: "It is not appropriate to use OLS residuals 
here. Please see documentation for details." We could discuss if this should be 
a flag or blocker (to get around a blocker version, people could just rename 
the field).

For background, see GeoDa Workbook, p. 193:
... it is not appropriate to use the permutation approach to assess 
significance [of global Moran's I for OLS residuals]. This is because OLS 
residuals are already correlated by construction and the permutation approach 
ignores this fact. For the same reason, it is also not appropriate to construct 
LISA maps for the residuals.

Not sure when we want to do this.  There is currently know easy way to know how 
a particual field was created: the user is fee to name any field whatever they 
want.

Great, I like that solution.  Let's leave the bug open until we update the new 
Tutorial so that we don't forget.  I suppose that we could create a Tutorial or 
Documentation update tag if we really wanted to.
