Arima_fit_impl

Low-Level ARIMA function for translating modeltime to forecast

internal

The time series forecasting framework for use with the 'tidymodels' ecosystem.
Models include ARIMA, Exponential Smoothing, and additional time series models
from the 'forecast' and 'prophet' packages. Refer to "Forecasting Principles & Practice, Second edition"
(<https://otexts.com/fpp2/>).
Refer to "Prophet: forecasting at scale"
(<https://research.facebook.com/blog/2017/02/prophet-forecasting-at-scale/>.).

of "auto" or time-based phrase of "2 weeks" can be used if a date or date-time variable is provided.</dd>
<dt>p</dt>
<dd>The order of the non-seasonal auto-regressive (AR) terms. Often denoted "p" in pdq-notation.</dd>
<dt>d</dt>
<dd>The order of integration for non-seasonal differencing. Often denoted "d" in pdq-notation.</dd>
<dt>q</dt>
<dd>The order of the non-seasonal moving average (MA) terms. Often denoted "q" in pdq-notation.</dd>
<dt>P</dt>
<dd>The order of the seasonal auto-regressive (SAR) terms. Often denoted "P" in PDQ-notation.</dd>
<dt>D</dt>
