BACKGROUND Monitoring of fur-bearing species populations is relatively rare due to their low densities. In addition to catch data, trappers' experience provides information on the ecology and status of the harvested species. Fisher (Pekania pennanti) and American marten (Martes americana) are mustelids that are sensitive to forest management and therefore considered to be ecological indicators ...

The paper presents closed form expressions and an algorithm for obtaining the Fisher information matrix of Gaussian single input single output (SISO) time series models. It enables the computation of the asymptotic covariance matrix of maximum likelihood estimators of the parameters. The procedure makes use of the autocovariance function of one or more autoregressive processes. Under certain co...

treatment. These rates agree with those reported by Ames ( 1966), but are higher than those reported by Fisher et al. (1959). However, the cost stated by Fisher did not include labor at $2.00 per man hour. Based on the number of trees killed, basal spray is an economical method to kill small and medium size trees (Table 4). Costs ranged from 11 to 18 cents per dead tree, depending on the size a...

The traditional way to find a linear solution to the feature extraction problem is based on the maximization of the class-between scatter over the class-within scatter (Fisher mapping). For the multi-class problem this is, however, sub-optimal due to class conjunctions, even for the simple situation of normal distributed classes with identical covariance matrices. We propose a novel, equally fa...

In this paper, we propose an improved filter selection method using Welch’s t-test based on discriminative filter bank common spatial pattern (DFBCSP). Existing DFBCSP used the Fisher ratio in order to find out discriminative filters. However, the Fisher ratio can be used to know only comparative value of distinguishability but may not become a meaningful criterion to reject null hypothesis. As...

In this paper we propose a new algorithm for face recognition named as Double Linear Discriminate Analysis (DLDA) in which we combine two linear discriminate methods: 2D-LDA and Fisher-face sequentially. Experimental results on benchmark face datasets show that DLDA not only achieves the best performance when the number of training samples is appropriate, but also its speed is the fastest among...

We apply the holonomic gradient method to compute the distribution function of a weighted sum of independent noncentral chi-square random variables. It is the distribution function of the squared length of a multivariate normal random vector. We treat this distribution as an integral of the normalizing constant of the Fisher-Bingham distribution on the unit sphere and make use of the partial di...
