This website is a collaborative work with Kanjirito, who has downloaded and parsed the JSON data on Warframe Rivens, with a lot of calculation done. Do check his GitHub repository to see how its done.
The parsed JSON data is presented in a nice, tabular format here, for easier filtering and searching. You can find out more about the JSON data in the forum announcement.
| Column name | JSON data key | Description |

Has it been rolled or unrolled (true/false)? |
| Avg | avg |
Average value of trades with this Riven Type. |
| Median | median |
The median in the prices that the Riven trades for. |
| StdDev | stddev |
The average variation in the prices that the Riven trades for. |
| Min | min |
Lowest amount of Platinum per trade of this Riven Type. |
| Max | max |
Highest amount of Platinum per trade of this Riven Type. |
| Pop | pop |
Popularity of this Riven Type being traded within all traded Rivens. |
| Est. Sales | N/A |
This is a derived value, based on the comment from /u/ghoust4 on how to estimate the amount of Rivens sold. It makes an assumption that a Riven with the same min, max, and average, with standard deviation of zero, should only have one Riven sold. From there, a ratio can be calculated based on the popularity, and the formula is applied across all the other Rivens. |
Kanjirito has made calculations on his script, which accumulates values up to one week before the specified week, and then a difference with the specified week is calculated. As an example:
// let's say, we are looking at the median for bronco riven, in week 3
week 1 median: 102
week 2 median: 209
week 3 median: 104
average of median across week 1-2: (102 + 209) / 2 = 155.5
median diff: 104 - 155.5 = -51.5
// or another, with the max for arca plasmor riven, in week 5
week 1 max: 102
week 2 max: 209
week 3 max: 82
week 4 max: 91
week 5 max: 672
average of max across week 1-4: (102 + 209 + 82 + 91) / 4 = 121
max diff: 672 - 121 = 551
From this differences, you can see the fluctuations of prices as the weeks go by.

We are missing some of the earlier Rivens data for some platforms, and the classic version I built does not make any archive of the data. If you have a copy of the data, do let Kanjirito know!
Otherwise, it is possible for the data to be ready, but not processed yet. Please be patient.
Its considered a classic now.
