Converting the annual trend equation to monthly or quarterly or half-yearly
If an annual linear trend is y = a + bx,
(1) The monthly trend with same origin month, x units of one year and y units of average monthly values will be y = a/12 + (b/12)x
(2) The monthly trend having origin in same month, x units of one month and y units of average monthly values will be y = a/12 + (b/12x12)x. So, y = a/12 + (b/144)x
(3) The Quarterly trend with the origin in same month, x units of one quarter and y units of average quarterly values will be
y = a/4 + (b/12x4)x
So, y = a/4 + (b/48)x
(4) The half-yearly trend with the origin in the same month, x units of half year and y units of average half-yearly values will be
y = a/2 + (b/2x12)x
So, y = a/2 + (b/24)x
