EXAMPLE
x = reshape([1:35],'1978a') // ceate an annual ts y = a2q(x) // gives an montly ts, from 1978q1 to 2012q4 with values 1 for all quarters of year 1978, // 2 for all quarters of year 1979... |  |  |
expand an annual series into a quarterly one
tsout=a2q(tsin)
* tsin = an annual time series
* tsout = the corresponding quarterly time series
x = reshape([1:35],'1978a') // ceate an annual ts y = a2q(x) // gives an montly ts, from 1978q1 to 2012q4 with values 1 for all quarters of year 1978, // 2 for all quarters of year 1979... | | |
