Hi everyone, I am interested in doing forecasting using triennial data (3-yearly data) in SPSS 26. I have done the necessary changes to the SPSS spreadsheet, namely, converting numerical into date type data, defining date and time as years, etc. However, The forecast timeline changes from say, 1989, 1992, 1995 to 1989, 1990, 1991. How can I change the forecast timeline to:
01-01-1989
01-01-1992
01-01-1995
01-01-1998
