Provides researchers and educators with easy-to-learn, user friendly
    tools for calculating key spatial statistics and for applying simple as well as
    advanced methods of spatial analysis on real data. These include: Local Pearson
    and Geographically Weighted Pearson Correlation Coefficients; Spatial Inequality
    Measures (Gini coefficient, Spatial Gini, Location Quotient (LQ) and Focal
    Location Quotient); Spatial Autocorrelation indices (Global and Local Moran's I);
    several Geographically Weighted Regression techniques, including the
    Geographically Weighted Zero-Inflated Poisson Regression; tools for computing
    variables used in Spatial Interaction Models; and other spatial analysis tools
    (other geographically weighted statistics). The local correlation tools were
    originally developed to test for local multicollinearity among the explanatory
    variables of local regression models and can also be used to examine the local
    association between pairs of variables. The package also contains functions for
    measuring the significance of each statistic calculated, mainly based on Monte
    Carlo simulations, and comes with two example datasets, one of which is a spatial
    data frame referring to the municipalities of Greece. Methods are described in

Analysis of stock data ups and downs trend, the stock technical analysis indicators function have trend line, reversal pattern and market trend.

Implements latent Dirichlet allocation (LDA)
	     and related models.  This includes (but is not limited
	     to) sLDA, corrLDA, and the mixed-membership stochastic
	     blockmodel.  Inference for all of these models is
	     implemented via a fast collapsed Gibbs sampler written
	     in C.  Utility functions for reading/writing data
	     typically used in topic models, as well as tools for
	     examining posterior distributions are also included.
