2.2.4.4 Winter's Method (Smoothing)

Winter’s method introduces a seasonal component /math-963123d6ba15e531cac42d449320e07c.png?v=0 "S_t")
in addition to the level /math-e1d5c4b15afff9fbc5ee69f570286302.png?v=0 "L_t")
and trend /math-fe8d284cdd689b2553a5388a966b67c9.png?v=0 "T_t")
components. The seasonal component captures the periodic fluctuations in the data.
