DISTINCTION BETWEEN SPEPECTRAL ANALYSIS AND HARMONIC ANALYSIS IN TIME SERIES ANALYSIS: EXPERIENCE FROM THE NUMBER CRUNCHER STATISTICAL SYSTEM (NCSS) SOFTWARE.	2020	12	.pdf	application/pdf	3097	126	66	In Harmonic analysis, one uses the frequencies identified from spectral analysis to form a model and harmonic analysis gives about eight different specific results as shown through Table 3 to Table 10.Fourier analysis is part of harmonic analysis, but in literature, most authors’ mistake spectral analysis for harmonic analysis and most statistical software’s also fall into the same misconception, but the use of the Number Cruncher Statistical System(NCSS), illustrates the role of either spectral analysis or harmonic analysis. Keywords: Harmonic analysis, spectral analysis, period, wavelength, model, forecasting.	cache/m-274.pdf	txt/m-274.txt
