Any opinions as to which software provides 'quality solutions' for BI
problems. Since we cannot send file attachments I am copying the text of
what all statistical and data mining techniques we are looking to cover and
attributes of software we are looking at (#options, ese of use, prices). All
input welcome.
Tools & Tech Name of Strong/ Flexibility #Options #Options

Non para - KS)
Latent Class Analysis
(mixture (of say 2 normals)
models)
Mapping/Graphs
