[FN] Statistical functions

Function

lnnormalden(z) Description: the natural logarithm of the standard normal density Domain: -1e+154 to 1e+154 Range: -5e+307 to -0.91893853 = lnnormalden(0)

lnnormalden(x,s) Description: the natural logarithm of the normal density with mean 0 and standard deviation s

lnnormalden(x,1) = lnnormalden(x) and lnnormalden(x,s) = lnnormalden(x/s) - ln(s) Domain x: -8e+307 to 8e+307 Domain s: 1e-323 to 8e+307 Range: -5e+307 to 742.82799

lnnormalden(x,m,s) Description: the natural logarithm of the normal density with mean m and standard deviation s

lnnormalden(x,0,s) = lnnormalden(x,s) and lnnormalden(x,m,s) = lnnormalden((x-m)/s) - ln(s) Domain x: -8e+307 to 8e+307 Domain m: -8e+307 to 8e+307 Domain s: 1e-323 to 8e+307 Range: 1e-323 to 8e+307
