Gaussian squared

WebIn laser science, the parameter M 2, also known as the beam propagation ratio or beam quality factor is a measure of laser beam quality.It represents the degree of variation of a beam from an ideal Gaussian beam. It is calculated from the ratio of the beam parameter product (BPP) of the beam to that of a Gaussian beam with the same wavelength.It … WebMar 6, 2024 · Applicability of R² to Nonlinear Regression models. Many non-linear regression models do not use the Ordinary Least Squares Estimation technique to fit the model.Examples of such nonlinear models include: The exponential, gamma and inverse-Gaussian regression models used for continuously varying y in the range (-∞, ∞).; …
