Nettet13. apr. 2024 · In multiquadratic radial basis function (MQ-RBF) interpolation, shape parameters have a direct effect on the interpolation accuracy. The paper presents an MQ-RBF interpolation technique with optimized shape parameters for estimating the parameters of sine wave signals. At first, we assessed the impact of basic sinusoidal … NettetN.M. Kiefer, Cornell University, Econ 620, Lecture 11 4 Aitken's Theorem: The GLS estimator is BLUE. (This really follows from the Gauss-Markov Theorem, but let's give a direct proof.)

The use of linear regression (least squares method) is the most accurate method in segregating total costs into fixed and variable components. Fixed costs and variable costs are determined mathematically through a series of computations.

NettetWe propose regularization methods for linear models based on the Lq-likelihood, which is a generalization of the log-likelihood using a power function. Regularization methods are popular for the estimation in the normal linear model. However, heavy-tailed errors are also important in statistics and machine learning.
