median

median

Calculate the median of the vector x.

Usage:

median(x)

median(x,q)

Parameters:

x

The data vector.

q

The cut point (0 < q < 1) or a vector of cut points. If no cut point is specified, 0.5 is used. If q is a vector, each element q[i] must be in the range 0 to 1.

Return Type:

scalar

Result:

The value xq with sum(h(x <= xq)) = q

If q is a vector the result is a vector xq with nrow(q) elements with: h(x | x<=xq[i]) = q[i]
