var_pop

sd_pop

<p>Calculate the population variance or standard deviation of a vector.</p>

Collection of convenient functions for common statistical computations,
which are not directly provided by R's base or stats packages.
This package aims at providing, first, shortcuts for statistical
measures, which otherwise could only be calculated with additional
effort (like standard errors or root mean squared errors). Second,
these shortcut functions are generic (if appropriate), and can be
applied not only to vectors, but also to other objects as well
(e.g., the Coefficient of Variation can be computed for vectors,
linear models, or linear mixed models; the r2()-function returns
the r-squared value for 'lm', 'glm', 'merMod' and other model objects).
The focus of most functions lies on summary statistics or fit
measures for regression models, including generalized linear
models, mixed effects models and Bayesian models. However, some
of the functions also deal with other statistical measures,
like Cronbach's Alpha, Cramer's V, Phi etc.
