gives you a range of statistics so you can analyze time-series data and predict events. It easily plugs into SPSS Base so you can seamlessly work in the SPSS environment.
Rich diagnostics check the fit of your models
SPSS Trends
generates statistics and normal probability plots to assess how models fit your data. Easily judge fit with automatically created standard errors and other statistics. You can also enhance your output using automatic, high-resolution charts. When you generate goodness-of-fit statistics, the display automatically separates the statistics for historical and validation periods so you see them side by side.
SPSS Trends has the procedures you need get the most from your time-series analysis. These procedures are:
- ARIMA: Produces maximum likelihood estimates for seasonal or non-seasonal time-series data.
- EXSMOOTH: Uses exponential smoothing methods to estimate up to four parameters in 12 different models.
- SEASON: Estimates multiplicative or additive seasonal factors for periodic time series.
- SPECTRA: Decomposes a time series into its harmonic components, sets of regular periodic functions at different wavelengths or periods.
- AREG: Estimates a regression model when the error from regression is correlated between one time point and the next.
