Sir pls tell about this question I am confused_ suppose the annual trend equation is generated by summing the quarterly time series values the equation is Tt=24+32t then the quarterly increase in trend values is
The coefficient of ‘x’, i.e. b/2 represents the increment in y-values on a half-yearly basis but one period in a year to the corresponding period in the following year. In order to obtain a half-yearly trend equation in which the ‘x’ values are also in units of one ‘half-yearly period’, and as the coefficient of ‘x’ represents an increment in trend values from half-yearly period to half- yearly period, the coefficient b/2 has to be further divided by 12. Thus, ultimately it becomes b/24.

Why X's coefficient is divided by 1/2 and 1/12 for half yearly

I am thinking about half-yearly, it should be b/4, not b/24. Still, I am confused.
Sir I think it must be b ÷4
