In statistics, multivariate adaptive regression splines (MARS) is a form of regression analysis introduced by Jerome H. Friedman in 1991. [1] It is a non-parametric regression technique and can be seen as an extension of linear models that automatically models nonlinearities and interactions between variables.
Thorvald Nicolai Thiele (24 December 1838 – 26 September 1910) was a Danish astronomer and director of the Copenhagen Observatory. [1] He was also an actuary and mathematician, most notable for his work in statistics, interpolation and the three-body problem.
Bennett et al. suggested adjusting inter-rater reliability to accommodate the percentage of rater agreement that might be expected by chance was a better measure than simple agreement between raters. [2]
In 1972, Herman Chernoff wrote an overview of optimal sequential designs, [25] while adaptive designs were surveyed later by S. Zacks. [26] Of course, much work on the optimal design of experiments is related to the theory of optimal decisions , especially the statistical decision theory of Abraham Wald .
Consumers could face higher prices for electronics if President-elect Donal Trump hits Canada, Mexico and China with new tariffs, Best Buy CEO said.
[1] [2] In order for the model to remain stationary , the roots of its characteristic polynomial must lie outside the unit circle. For example, processes in the AR(1) model with | φ 1 | ≥ 1 {\displaystyle |\varphi _{1}|\geq 1} are not stationary because the root of 1 − φ 1 B = 0 {\displaystyle 1-\varphi _{1}B=0} lies within the unit circle.
