OCR: The Periodogram Data Table the active data table has rows then the new periodogram table has M rows, where M N/2 1 if N even, or N 1)/2 if N is odd. M IS used to form the white noise test statistics described later The columns in the JMP data table are Period (wavelength) 2N*Freq Cycles per observation period Frea Freq freguency in radians and ranges from 0 to p. To express frequency in cycles per unit time (such as cycles per year) compute (d*Freq)/2p where dis the number of observations per unit time The period of the cycles then 2p/(d*Freq) Sine andCosine are the sine and cosine coefficients for each row used to compute the periodogram for that row. The com iputations for Sine and Cosine ca found in the SAS/ETS User Guide Version (1988) Periodogram the periodogram plot ordinate (d) for ...
