descriptiveSummary(x)
x |
Vector of observations. |
The function descriptiveSummary()
gives a descriptive statistics of the
data containing: mean (overline{x}), median, mode, standard deviation (s),
coefficients of variation, skewness and kurtosis, range, minimum, maximum and the number
de observations. This function uses the command searchMode()
that allows
to find the empirical mode of the data.
Sample coefficient of variation (CV):
mbox{CV}=frac{S}{overline{X}}times 100 quad (rm{in} %).
Sample coefficient of skewness (CS):
mbox{CS}=frac{1}{n}frac{sum_{i=1}^{n}(X_i-overline{X})^3}{S^3}.
Sample coefficient of kurtosis (CK):
mbox{CK}=frac{1}{n}frac{sum_{i=1}^{n}(X_i-overline{X})^4}{S^4}-3.
The function descriptiveSummary()
carries out a descriptive summary of the data.
