QUESTION
I am trying to use the pymatch package but I keep getting the error Error: Perfect separation detected, results not available
. I checked multiple times, my dataset is not equal. It contains 260k rows for Control and 50k for treatment and has different averages. I only have 5 variables, all integers
or Floats
rounded to 2 decimals.
My goal is to match some treated customers to non-treated customers for further analysis based on propensity score matching.
I already removed outliers as apparently it cannot handle these well. I also rounded Decimals to 2 positions after the comma. I tried using only 2 variables of the whole dataset. Nothing worked.
...ANSWER
Answered 2019-Jun-27 at 13:07I solved the issue myself. By the nature of the data, one variable
was affected by the treatment. Meaning that no datapoint in was_treated== 1
could have a Miles_away >10
and vice versa, no datapoint in was_treated== 0
could have Miles_away <10
. This was the perfect separation. Excluding this variable
from the propensity scoring solved the issue.
QUESTION
I'm developing on the re module in rustpython using the regex
crate. I want to store the Match
object in a struct without lifetimes. Is there a way to do this?
So far, I simply copied the start
and end
values of the match object into seperate fields, but this feels odd and wrong. There should be a way to store the Match
object itself. (Corresponding code lives here: https://github.com/RustPython/RustPython/blob/master/vm/src/stdlib/re.rs#L78)
ANSWER
Answered 2019-Jul-11 at 20:16You can't remove the lifetime of the Match
object, because it is defined like so:

Install PyMatch
You can use PyMatch like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
