PopulationStat function

Population statistics

Provides theoretical descriptive statistics.

populationstat(stat = "mean", dist, distarg, p0 = 0, distbounds = c(-Inf, Inf))

popmean(dist, distarg, p0 = 0, distbounds = c(-Inf, Inf))

popsd(dist, distarg, p0 = 0, distbounds = c(-Inf, Inf))

popvar(dist, distarg, p0 = 0, distbounds = c(-Inf, Inf))

popcvar(dist, distarg, p0 = 0, distbounds = c(-Inf, Inf))

popskew(dist, distarg, p0 = 0, distbounds = c(-Inf, Inf))

popkurt(dist, distarg, p0 = 0, distbounds = c(-Inf, Inf))

Arguments

• stat: define what you what to calculate - possible population desc. statistics ('mean', 'sd', 'var', 'cvar', 'skew', 'kurt')
• dist: distribution
• distarg: list of distribution arguments
• p0: probability zero
• distbounds: distribution bounds (default set to c(-Inf, Inf))

Examples

populationstat('sd', 'norm', list(mean = 2, sd = 1))
populationstat('var', 'norm', list(mean = 2, sd = 1))
populationstat('cvar', 'norm', list(mean = 2, sd = 1))
populationstat('skew', 'norm', list(mean = 2, sd = 1))
populationstat('kurt', 'norm', list(mean = 2, sd = 1))
