##### Column Statistics

A collection and description of functions to compute column statistical properties of financial and economic time series data. The functions are:

 colStats calculates column statistics, colSums calculates column sums, colMeans calculates column means, colSds calculates column standard deviations, colVars calculates column variances, colSkewness calculates column skewness, colKurtosis calculates column kurtosis, colMaxs calculates maximum values in each column, colMins calculates minimum values in each column, colProds computes product of all values in each column,

Keywords

##### Usage
colStats(x, FUN, ...)
colSds(x, ...) colVars(x, ...) colSkewness(x, ...) colKurtosis(x, ...) colMaxs(x, ...) colMins(x, ...) colProds(x, ...) colQuantiles(x, prob = 0.05, ...)
colStdevs(x, ...) colAvgs(x, ...)
##### Arguments
FUN
a function name. The statistical function to be applied.
prob
a numeric value, the probability with value in [0,1].
x
a rectangular object which can be transformed into a matrix by the function as.matrix.
...
arguments to be passed.
##### Value

the functions return a numeric vector of the statistics.
