According to the reference manual, the test was suggested by Pregibon
(1979) based on an idea of Tukey (1949). It also says that Pregibon (1980)
suggested a slightly different method that has come to be known as
"Pregibon's goodness-of-link test" - but Stata uses the older version
because it is universally applicable. So, I'm not sure if there is a name
for the test, but there is a source for it.
what is the real name of the test called "linktest" in Stata?Is there an
Collin reports 2 sets of numbers that are both called the condition
index. I'm not sure if they have separate names or not. The difference is
in the estimation, i.e. with index 1 variables are centered about their
means first and in index2 they are not. My intuition leads me to favor
approach 1 but it turns out there is a lot of controversy on this. Belsley
Kuh and Welsch discuss this in their 1980 book on regression diagnostics.
And the real name of the Condition Index1 (collin)???
Many many thanks...
