and21). This chapter shows that not only the mean but also the variance may be modeled. In classical statistics, variance modeling may be rather hard and fairly obscure in its application to anecologist. In contrast in WinBUGS, the modeling of variances, e.g., as a function of some covar...
In statistics, it is the average of the squared differences from the Mean. Can numpy.var() handle multi-dimensional arrays? numpy.var() can handle multi-dimensional arrays. You can specify the axis along which the variance is calculated for multi-dimensional arrays. How can I calculate the ...
The major problems, their background, and the related concepts are clearly described with many figures and examples. Some necessary mathematical and statistical concepts and techniques are also introduced in a way that readers without much training in mathematics or statistics can easily understand. ...
