1T – Univariate & Bivariate Spectral Analysis

Univariate & Bivariate Spectral Analysis using BMDP Statistical Software Program 1T

The data screening and analytical methods in 1T are applicable to a wide variety of time series data and can be extended to pairs of series.

• Frequency domain approach
• Graphical and numeric displays of periodograms and spectra of single or pairs of time series
• Filtering and optional re-coloring
• Estimates of degree of coherence and regression relation between two time series in different frequency bands
• Smoothing by removing seasonal means or linear trends or by constructing filters
• Confidence intervals about spectral estimates
• Option to save various results from spectral estimates
