periodogramn.

Brit.

/ˌpɪərɪˈɒdəɡram/, U.S.

/ˌpɪriˈɑdəˌɡræm/,

/ˈpɪriədəˌɡræm/

Origin: Formed within English, by compounding. Etymons: period n., -o- connective, -gram comb. form.

Etymology: < period n. + -o- connective + -gram comb. form. Compare slightly later periodograph n.

Chiefly Science.

A diagram or method of graphical representation which is designed to detect or display any periodicity (usually with time) in a set of measurements; spec. one in which the results of harmonic analysis of the data, performed on the assumption in turn of different periods of variation, are plotted as a function of the period.

1898 A. Schuster in Terrestrial Magn. 3 24 It is convenient to have a word for some representation of a variable quantity which shall correspond to the ‘spectrum’ of a luminous radiation. I propose the word periodogram.

1906 Proc. Royal Soc. A. 77 141 The periodigram..is the diagram representing the intensity of periodic variations as determined from the sum of the squares of the two Fourier coefficients belonging to each assumed period.

1974 Nature 8 Feb. 339/3 The apparently erratic optical fluctuations have been analysed by various investigators using power spectra and the so-called periodogram techniques.

2003 Applied Econ. (Nexis) 20 Mar. 541 This regression is performed using the first n(T) values from the sample periodogram.
