A ratio estimation model based on the inverse Gaussian distribution is presented, together with a complete and exact system of inference procedures. The system is an analogue of that for the normal model, involving inferences based on χ2 and F distributions. A case illustration and a discussion...

The inverse Fourier Gaussian filter is simply the reciprocal of Eq. (16.11). Since a reconstructed image is band limited, due to the discretization process, the inverse filter will have a cutoff frequency, kmax≤12Δr, where Δr is the pixel/voxel width, see Eq. (12.11). Therefore, the...

In this work we introduce a new frailty model for clustered survival data using the Generalized Inverse-Gaussian (GIG) distribution for the frailty. Assuming this distribution implies in a exible model thatis mathematically advantageous since closed expressions are avaliable for the unconditional survival...
也就是说,利用 Tweedie's formula 的 mean estimate 构造一个 Gaussian. 接着带入公式 p_t(y|x_t)=\int_{x_0}p_t(x_0|x_t)p(y|x_0)dx_0 进一步计算出 p_t(y|x_t)\approx\mathcal{N}(H\hat{x}_0(x_t),r_t^2HH^{\top}+\sigma_y^2I) 最后两边取 \log\nabla_{x_t} 得...
Thus, we propose the inverse Gaussian-beam stack imaging, in which Gaussian weight functions of rays contributing to the geophones energy are calculated and used to decompose the seismic wavefield. This effectively enlarges the coverage of the reflection points and improves the transverse resolution. ...
it is converted into a Gaussian mode, which efficiently couples into an SMF positioned in the far field of the first-order diffraction spot. The SMFs guide the filtered photons to superconducting nanowire single-photon detectors (Quantum Opus, Opus One; efficiency, >90% at 810 nm). Coinciden...
