Purpose

Summarizing statistics for sample data.

Synopsis

summ = sumary(x)

INPUTS

  • x = matrix (column vector) in which the sample data is stored.

Outputs:

The return value is a structure with fields:

  • mean = mean of the sample
  • std = standard deviation of the sample
  • n = number of observations
  • min = minimum value in the sample
  • max = maximum value in the sample
  • p10 = tenth percentile
  • p25 = twenty-fifth percentile (lower quartile)
  • p50 = fiftieth percentile (median)
  • p75 = seventy-fifth percentile (upper quartile)
  • p90 = nintieth percentile
  • skew = skewness
  • kurt = kurtosis

Examples

summ = summary(x);
