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

Dear Lazar, I'm doing the measurement and structural model and there is a result, but there is a notification: Matrix to be analyzed is not positive definite, ridge option taken with ridge constant = 0.100. Help me to solve it.

I am confused what you mean by this.

"Well don't put them into the model as dummies - put them in as a categorical so you have control. " What is the difference between a dummy variable and a categorical variable?
