Is there an Ability to explicitly define Distributions?

[clj2567]

When I create synthetic rowsets using sampl_rows, one thing I noticed is that it assumes that my distribution is Normal and therefore it skews the values. For example, the secs elapsed field doesn’t have a negative value in my original dataset but in the synthetic ones it contains negative values ranging from -4000 to +6000. Is there any way I can specify the Distribution for each column?

Hi @clj2567

There is a way to indicate which distribution to use, but currently this setting affects all the columns, so you cannot choose a custom distribution per column. This is a feature that will be added in the future.

Also, regarding sampling negative values, this would be better taken care of by the data constraints functionality that is also being developed. See #70

I hope this clarifies your doubts!
