Teaching Policy Instrument Choice in Environmental Law: The Five P’s [PDF]
, 2013 . We introduce a method to combine the color channels of an image to a scalar valued image. Linear combinations of the RGB chan-nels are constructed using the Fisher-Trace-Information (FTI), defined as the trace of the Fisher information matrix of the ...

A MULTIVARIATE WEIBULL DISTRIBUTION
Pakistan Journal of Statistics and Operation Research, 2010 A multivariate survival function of Weibull Distribution is developed by expanding the theorem by Lu and Bhattacharyya (1990). From the survival function, the probability density function, the cumulative probability function, the determinant of the Jacobian Matrix, and the general moment are derived.

Maximum likelihood and pseudo score approaches for parametric time-to-event analysis with informative entry times [PDF]
, 2014 We develop a maximum likelihood estimating approach for time-to-event Weibull regression models with outcome-dependent sampling, where sampling of subjects is dependent on the residual fraction of the time left to developing the event of interest ...
