functional magnetic resonance imaging (fmri) is a safe and non-invasive way to assess brain functions by using signal changes associated with brain activity. the technique has become a ubiquitous tool in basic, clinical and cognitive neuroscience. this method can measure little metabolism changes that occur in active part of the brain. we process the fmri data to be able to find the parts of br...

There is a common belief that the presence of residual spatial autocorrelation in OLS regression leads to inflated significance levels in beta coefficients, and in particular, inflated levels relative to the more efficient Spatial Errors (SE) model. However, simulations show that this is not always the case. Hence the purpose of this paper is to examine this question from a geometric viewpoint....

One of the characteristics of environmental data, many of them and the complex relationships between them. To reduce the number variables, different statistical methods exist. Multivariate statistics is used extensively in environmental science. It helps ecologists discover structure and previous relatively objective summary of the primary features of the data for easier comprehension. However,...
