Output data format

Output periodograms are computed at constant frequency steps and stored in the first row of an image. The second row of this image contains some information on the quality of the periodogram, specific for each method. Both can be conveniently plotted with the PLOT/ROW command. WIDTH/TSA is available for a first analysis.

Output time lag functions, resulting from the analysis of aperiodic signals, are stored in a table containing the columns :LAG and :FUNCT. They can be inspected by with standard MIDAS table commands such as PLOT/TABLE or READ/TABLE.
