Following the identifiers you get these

Full choke:
Pellet spread modifier 0.6
Moving ADS and moving/stationary HIP modifier 1.5 (stationary ads unaffected)
Vertical and horizontal recoil modifier 1.5

Modified choke:
Pellet spread multiplier 0.8
Moving ADS/HIP modifier 1.25 and stationary HIP 1.5
Vertical and horizontal recoil modifier 1.5

Duckbill:
Horizontal pellets spread modifier 1.5
Vertical pellets spread modifier 0.4
No change in gunsway (recoil or ADS/Hip spread)

Are the modifiers for the Duckbill and Chokes still the same as they are listed above, or have they since been changed by DICE?
The post was made in 2013, so I think its worth asking about.

They have changed bit:

Mod Choke:
  • 0.875x dispersion
  • 1.25x movement penalty on spread during ADS

Full Choke:
  • 0.75x dispersion
  • 1.5x movement penalty on spread during ADS
  • 1.2x min HIP spread

Duckbill Choke:
  • 1.5x horizontal, 0.4x vertical dispersion

Did they take away the recoil modifiers though?

Yeah. For pump actions it has close to zero impact on accuracy, and with semi-autos it still can be compensated unless you use slugs, in which case you shouldn't be using chokes (except duckbill. Always use duckbill with slugs/frags because why not).

Yeah, I figured the chokes wouldn't be good with Slugs, and lol @ Duckbill with Slugs.
The part where I'm confused though is when you pair Slugs with a Compensator or Muzzle Brake, especially with a Compensator. This is where I think Accuracy Plots should come in.

As an extensive user of shotgun slugs (because I can't hit things with buckshot - don't ask me why), I've thought about having an Accuracy Plot for this as well.
For the Saiga-12K, DBV-12, and the DAO-12, I occasionally use muzzle brakes with frag rounds and slugs, it depends on whether or not my game is good that night/day.
However, with the M1014 and QBS-09, I use compensators. For whatever reason, I find that it helps me just enough to where I can unload three slugs into someone at 30+ meters.

It'd be nice to see a plot that showed whether or not I was making a horrible mistake!

Side note, moving while emptying the QBS-09 and hip-firing without a laser pointer makes for some pretty wickedly inaccurate shooting.
I love the math behind the statistics
It's possible to find me online at almost any given time, due to the fact that my schedule is hectic and rather non-existent.

What I do not understand are the spread values for the chokes.

The hip penalty for the full choke, what exactly does it mean? Does it mean that the spread is applied to the entire cone of pellets or to each pellet itself?

I am especially interested in this because I get much better results from using flachette in combination with a modified choke instead of the full choke, especially on maps like pearl market where hip fire is obligatory.

Shotguns have two types of "spread":

Normal spread - When you fire a shwoi with any gun the game will first calculate "central point" that deviates from center aimpoint (ie. your crosshair) at most this angle. For shotguns this changes the middle point of the center of pellets. (This is uniform distribution)
Pellet dispersion - This is the unique part of shotguns (the circle crosshair). When you fire a shot your pellets will spread around central point of the shot at most this angle (also note that the focus is in middle, so being accurate with shotguns rewards).

So basically firing hip shots with full choke on might deviate the shot way off from target. Especially with pellet spread having focus in middle (not gaussian-normal, something sharper) this really reduces the damage output.

Ahh so actually the full choke increased spread penalties which are applied to the entire cone, which is thinner than modified, will make me miss more pellets. Especially on follow-up shots which are necessary to put down a target most of the time, with semi-autos at least.
