The Lax Proof of the Change of Variables Formula, Differential Forms, a Determinantal Identity, and Jacobi Multipliers Nikolai V. Ivanov September 4, 2001 Introduction. In a beautiful paper [Lax1], P. Lax presented an elemen- tary proof of a special case of the change of variables theorem....
摘要: In this paper we investigate the asymptotic properties of the test statistics for detecting change-points in the variance of infinite moving average sequences with long memory.关键词: Change of variance Limiting distribution Linear process Long memory ...

we extract different sets of variables from individuals’ participation in partisan sociopolitical groups28. We then use this information to test three alternative sets of confounders. First,individual political sides: whether each of the two involved individuals participates to a left- or right-wing ...
Our main theme are order patterns in day-to-day financial data and their statistics. The zigzag patterns of up and down have long been considered by stock traders. Today they are certainly incorporated in secret algorithms for high-frequency trade. We are interested in the statistical error of...
Climate change is a critical factor affecting biodiversity. However, the quantitative relationship between temperature change and extinction is unclear. Here, we analyze magnitudes and rates of temperature change and extinction rates of marine fossils th
Simple statistical values can enable us to clearly grasp the overall picture of the data, and fully understand and identify the concentration or dispersion of the data. Therefore, this paper uses the descriptive statistical variables including arithmetic average (“Aver”), maximum (“Max”), ...
Variables included were tested for association using univariate statistics, and collinearity tested using variance inflation factors (VIF). All variables with high VIFs, including relative humidity which was highly collinear with temperature and rainfall, were excluded. Summaries of these pre-analysis ...
These variables have been applied to SDMs of bumblebee species in the past39,40,50. Further, annual mean temperature and annual precipitation are among the most representative of climate data since they are not derived from other variables48. General circulation models (GCMs) at 5 arc-minutes ...
