# Data

Each row of the dataset describes an investment vehicle at a certain date.

Here follows a concise description of the columns of the three files comprising the dataset, `X_train` and `y_train`.

`X_train`:

* `date`: A sequentially increasing integer representing a date. Time between subsequent dates is a constant, denoting an unknown but fixed frequency at which the data is sampled. The initial training dataset is composed of 268 dates. 
* `id`: A unique identifier representing the investment vehicle at a given date. Note that the same asset has a different `id` at each date.
* `0,...,460`: Anonymized features describing an investment vehicle at a given date. Derived from high-quality market data.

`y_train`:

* `date`: Same as in `X_train`.
* `id`: Same as in `X_train`.
* `y`: The target value to predict. It is related to the future performance of the investment vehicle at the given date. The value is normalized between `-1` and `1`.

`X_test`:

* Same structure as `X_train` but comprises only a few dates. This file is used to simulate the submission process locally via `crunch.test()`, or `cruch test`. The aim is to help participants debug their code and have successful submissions. A successful local test usually means no errors during execution on the submission platform.

The dataset is obfuscated.
