docs: fixed import typo in UserGuide - Data Preparation

[klein-baru]

from mlfinpy.datasets import (load_tick_sample, load_stock_prices, load_dollar_bar_sample)

# Load sample tick data
tick_df = load_tick_sample()

Note

This raises import errors, the correct syntax ought be, from mlfinpy.dataset not datasets

from mlfinpy.dataset import (load_tick_sample, load_stock_prices, load_dollar_bar_sample)

# Load sample tick data
tick_df = load_tick_sample()
