All catalogs
have errors, which may render
|
|
|
|
invalid
conclusions derived in a study based on a
|
|
|
catalog of
earthquakes.
|
|
|
Two ways to
avoid the errors –
|
|
|
l |
Postpone the
analysis until the data are refined;
|
|
|
l |
Use robust
methods within the limits of their
|
|
|
applicability.

“Undue
precision of computations is the first

symptom
of mathematical illiteracy”
