Programmer Guide/Command Reference/EVAL/median

Compute median or quantiles of a vector x.

The quantile q_p can be defined as the probability p such that an element of x is lower than q_p. The value p must be in the range 0 to 1. The special quantile q_0.5 is also called median.

Usage 1

median(x_vector {, p_scalar })

x

data vector

p

the propability; 0 < p < 1 (default=0.5)

Result 1

Returns the p-quantile (scalar) of x.

---

Usage 2

median(xvector , pvector })

x

data vector

p

vector with propability values

Result 1

Returns a vector containing the quantiles for all probabilities p[i].
