# lncdfnc¶

## Purpose¶

Computes natural log of complement of Normal cumulative distribution function.

## Format¶

y = lncdfnc(x)
Parameters: x (NxK matrix) – values at which to evaluate the complement of the cumulative distribution function. y (NxK matrix) – the natural log of the complement of the cumulative distribution function. $ln\ (1 - Pr(X < x))$

## Examples¶

// Value to compute
x = 0.5;

// Compute complement of the cdf
pc = cdfnc(x);

// Compute ln of the complement of the cdf
lnpc = lncdfnc(x)

print "pc ="; pc;
print "ln(pc)"; lnpc;

pc =
0.30854
ln(pc) =
-1.17591
