# ds1000 / 891 - taskset: [ds1000](https://harnessreport.com/tasks/ds1000.md) - difficulty: - category: - language: - runnable from the site: no - agent timeout: 1800s ## Results by harness _none yet_ ## Instruction ``` # 891: DS-1000 Task ## Prompt Problem: Is there any package in Python that does data transformation like Yeo-Johnson transformation to eliminate skewness of data? I know about sklearn, but I was unable to find functions to do Yeo-Johnson transformation. How can I use sklearn to solve this? A: <code> import numpy as np import pandas as pd import sklearn data = load_data() assert type(data) == np.ndarray </code> yeo_johnson_data = ... # put solution in this variable BEGIN SOLUTION <code> ## What to do - Edit `solution/solution.py` so the code passes the DS-1000 tests. - Do not access the internet or install new packages; required libraries are preinstalled in the Docker image. - Run tests locally via `bash tests/test.sh`. ## Notes - Keep the variable names/signatures implied by the prompt/code_context. - The evaluator uses the original DS-1000 `code_context` (`test_execution` / `test_string`). ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
