    Abstract: An analysis apparatus includes a light emission unit configured to emit measurement light including light in a 900 nm wavelength band to a sample, a light detection unit configured to acquire spectrum data of reflected light in the sample, a data processing unit configured to perform a noise removing process on the spectrum data, a first determination unit configured to store a PLS regression model associated with prediction of an amount of triglyceride in the sample and to determine an amount of triglyceride in the sample by applying the spectrum data subjected to the noise removing process to the PLS regression model, and a second determination unit configured to store data indicating a correlation with an amount of triglyceride in the sample and to determine an amount of brown adipose tissue or beige fat in the sample based on the data and the amount of triglyceride determined by the first determination unit.

    Abstract: A phantom design method includes a correction step and a calculation step. In the correction step, an absorption spectrum of a target of spectroscopic measurement by a near infrared spectrometer is corrected based on a refractive index of the target and a refractive index of a resin used as a base material of a phantom to generate a corrected absorption spectrum. In the calculation step, based on an absorption spectrum of the resin and an absorption spectrum of each of N types of dyes, a concentration of each of the N types of dyes to be contained in the base material is calculated such that an absorption spectrum of the phantom constituted by the base material containing the N types of dyes approximates the corrected absorption spectrum in a predetermined wavelength range of a near infrared region.
