Statistical functions

[Jim Labos - infobase via 4D_Tech]

Does anyone know of a plug-in or component that  computes statistics:
t-tests, analysis of variance, correlation coefficients, chi-square etc.?

Thanks

Difficulties implementing a functional approach arise from only being able to 
do certain things with mutable data structures. Programming languages that 
support a functional approach usually support both mutable and immutable data 
structures. A database is inherently mutable, so I suppose that part makes it 
difficult to begin with.

It works well for highly parallel systems and some newer languages were 
designed with functional support features specifically for this purpose. For 
example see Clojure, Haskell, and Erlang.

[RECOMMENDED] Panorama X Database Software for Macintosh

[Walt Nelson via 4D_Tech]

Folks,

http://www.provue.com/winterfest2017/ 

For you long time Mac users, you will probably remember ProVUE Development - 
James Rea - I used his database product BEFORE I used 4D (it was available 
before 4D shipped in 1987).

His latest product is called Panorama X - previously I used Panorama Sheets 
from the Mac App Store.

Why am I telling you about another database product on the 4D NUG?

Here are my use cases:

Raw Data Cleanup - if you ever have to bring in data from another system, 
you’ve probably written some custom code in 4D to clean up the data on import. 
I use Panorama X to interactively clean up data before importing. You can 
script Panorama X to do this if you need to repeat your cleanup many times. I 
love the multiple undos when I screw up the data!

Data Browsing - ever wonder what all your data in 4D ‘looks like’? Tried 
browsing your data in the debugger? I export the changes my code hath wrought 
to the data and check it in Panorama. No more creating a layout to check your 
data in the old ‘User Environment’.

Data Analysis - if your client wants some sophisticated stats on their data - 
just export and build a nice custom report w/stats quickly in Panorama. 
Includes mapping presentation for GeoData.

Some features:
RAM based - lightning fast
Programmable interface
JSON support
Multi-level Undo and Redo
Record ‘Macros’ like in Excel or use their programming language

Downsides:
Flat File - not relational
One more language/interface to learn - not necessary bad, but something to 
consider
Mac Only - again, not bad - you Windows folks need to wise up ;-)

System Requirements: macOS 10.9 or later

Unique payment model, too. Pay only when you USE the product. See this video 
for details: https://vimeo.com/230711355 
No credit card required for the 7-day trial.
No email address required.
Trial days do not have to be contiguous.
It is so refreshing to have such liberal trial policies.

Do yourself a favor and check this out over your holiday break. You can thank 
me later. ;-)

The WINTERFEST2017  deal 
is 25% off for a limited time.

Watch the 19 minute video on their sales page for complete details.

Not affiliated with ProVUE at all. Just love what James Rea (& his bro, Steve) 
have provided over the years. These guys are part of the GOOD GUY club.

Look forward to hearing what folks think of this product. I will be using this 
to browse my horse racing data, for sure.

Thanks,
Walt Nelson (Seattle)
New stuff coming!
