Handling of missing values in statistical software packages for windows
The problem of estimating parameters of distributions by an incom plete data set is theoretically considered but in practice the implementa tion of the developed methods in commercial statistical software packages varies from program to program None of the examined software o ers all possible methods In some programs the user has no choice concerning the use of a method or no methods at all are...
متن کاملRecursive Algorithms for Image Local Statistics in Non-rectangular Windows
A general framework is presented for recursive computation of image local statistics in sliding window of almost arbitrary shape with “per-pixel” computational complexity substantially lower than the window size. As special cases, recursive algorithms are described for computing image local statistics such as local mean, local variance, local kurtosis, local order statistics (minimum, maximum, ...
متن کاملExtending the Use of Statistical Packages in an Elementary Statistics Course to Enhance Understanding
There is a growing literature advocating the use of in-class sampling experiments to help build statistical intuition and to make the subject matter less abstract and more directly accessible to the student. The author has developed a number of such experiments in relation to correlation and regression, different sampling methods and hypothesis testing. They are used in conjunction with class d...
متن کاملUsing Collaborative Learning Packages to Teach Introductory Statistics at the Post - Secondary Level
Amongst statistical educators there is a wide ranging debate about both the pedagogy and content of the first University level course in Statistics. This paper describes the use of collaborative learning groups as a replacement for the traditional lecture / tutorial mode of teaching in an Introductory Statistics course. The materials used to support this learning approach reflect the wider view...
متن کاملEffects of temperature on Agrocybe chaxingu quality stored in modified atmosphere packages with silicon gum film windows
The effects of three storage temperatures (1, 3, and 5 1C) were determined on the quality of the edible mushroom Agrocybe chaxingu stored in modified atmosphere packages (MAP) with and without (control) silicon gum film windows. Results showed that the storage temperature had clear effects on headspace gas concentrations of O2, CO2 and ethylene, sensory characteristics, respiration rate, ascorb...
