Hello everyone!
Since this is my first article here on SixPrizes I will start off by introducing myself. My name is Steffen Eriksen and I am currently doing my bachelor in Mathematic-Economics in Denmark. I have been playing Pokémon TCG for around 6 years and have played tournaments in many countries.
The article is about the data collection process for my bachelor, which I hope you will be a part of.
Some time ago I got an idea about a so-called “win-rate” model for the Pokémon TCG, so I asked my university if I could write my bachelor project about this model and I got a yes! So now I have this huge opportunity to write my project about my hobby, which is really cool!
To explain a little more about what this win-rate model, it is a model where I try to explain what will affect a Pokémon player’s win-rate. What I mean when I say win-rate, is how many percent of your premier rated games you have won.
The methods I will use to estimate such a model is generally different types of regression models, which is borrowed from econometrics.
This model I can then use to answer some hypothesis I will state in the beginning of my paper. Such a hypothesis could be: Will playing the game for a longer time give you a higher win-rate?
So I will with this model maybe be able to answer some pretty interesting hypotheses about the game.
Before I can even start thinking about setting up such a model I need data from Pokémon players. Unfortunately I can not just use data from every player out there. I have to make some certain conditions in order to make my model valid. I will state these 3 conditions and if you do not fulfill all 3 of the conditions below I will not be able to use your contribution.
Condition 1 – Masters Division Only
I have chosen only to make this model for players in the Masters divison. This is done because in different age division there might be different decks which does well. For example in the Junior division a “Speed Jumpluff” deck might do well.
However I do not think that such a deck will do well in the master division. So such a sample will give a misleading picture of my model and maybe show that the highest win-rate will be achieved with a “Speed Jumpluff” deck, when it in reality not is. (Sorry to all Jumpluff fans out there).
Condition 2 – Results from This Season Only – Prior to B/W
I am only working with the current season. So all questions below assume the current season. It is then your tournament record from the 1st of September until now that counts.
If you have already played with B&W and the new rules (e.g. in the USA) then it is your tournament record from Regionals and back that counts.
The reason why I will not take B&W into account is because it will have too big of an impact on the decks that are being played and also increase the luck factor even more.
Condition 3 – You must have played at least 25 Premier Rated games
You have to have played at least 25 premier rated games this season. The reason for this is that with a low number of games played will give a more unstable win-rate. A single loss will lower your win-rate too much when your number of games played is below 25.
Then you might ask yourself, why 25 and not 30, 35, or 42 (which is the answer to everything). I just have to pick a suitable number. Picking a to low number will give unstable win-rates. Picking a too high one will result in too few samples.
So after stating these 3 conditions I can now go on to the actual questions. All questions are simple and can be answered right away, except for the last 2, which requires you to log onto your Pokémon account on Pokemon.com, unless of course you can remember by heart how many games you have played this season and how many you have won.
You also have to answer all the questions, otherwise your contribution will not be valid.
Here are the questions:
What country are you from?- How old are you?
- How many years have you played the game? (approximately)
- What type of deck have you used the most this season? (Examples: LuxChomp, BlazeChomp, VileGar, LostGar, DialgaChomp, MagneRock, Gyarados, MewDos, etc…)
- Do you have a full-time job? (Full-time student does not count as a job for this question.)
- Are you a Pokémon Professor?
- Have you played a Premier Rated tournament abroad this season? (For players in the US, I count playing in a different state as playing abroad.)
- Do you have family members who also play the Pokemon TCG?
- How many Premier Rated games have you played this season? (You can check on your My Pokemon account.)
- How many of those games have you won? (This you can check on your my-pokemon account.)
