Trend
Calculates the trend of a column over time.
Given a list of values and a corresponding list of datetimes, calculate the slope of the linear trend of values.
Examples
>>> from datetime import datetime >>> trend = Trend() >>> times = [datetime(2010, 1, 1, 11, 45, 0), ... datetime(2010, 1, 1, 11, 55, 15), ... datetime(2010, 1, 1, 11, 57, 30), ... datetime(2010, 1, 1, 11, 12), ... datetime(2010, 1, 1, 11, 12, 15)] >>> round(trend([1, 2, 3, 4, 5], times), 3) -0.053
