LOGSDF Function

Computes the logarithm of a survival function

Category: Probability

See: 'SDF Function' on page 817

Syntax

LOGSDF ( 'dist',quantile,parm-1,...,parm-k )

Arguments

'dist'

• is a character string that identifies the distribution. Valid distributions are as follows :

  Distribution	Argument
  Bernoulli	'BERNOULLI'
  Beta	'BETA'
  Binomial	'BINOMIAL'
  Cauchy	'CAUCHY'
  Chi-Square	'CHISQUARE'
  Exponential	'EXPONENTIAL'
  F	'F'
  Gamma	'GAMMA'
  Geometric	'GEOMETRIC'
  Hypergeometric	'HYPERGEOMETRIC'
  Laplace	'LAPLACE'
  Logistic	'LOGISTIC'
  Lognormal	'LOGNORMAL'
  Negative binomial	'NEGBINOMIAL'
  Normal	'NORMAL''GAUSS'
  Normal mixture	'NORMALMIX'
  Pareto	'PARETO'
  Poisson	'POISSON'
  T	'T'
  Uniform	'UNIFORM'
  Wald (inverse Gaussian)	'WALD''IGAUSS'
  Weibull	'WEIBULL'

• Note: Except for T, F, and NORMALMIX, you can minimally identify any distribution by its first four characters .

quantile

• is a numeric random variable.

parm-1, ,parm-k

• are optional shape , location , or scale parameters appropriate for the specific distribution.

The LOGSDF function computes the logarithm of the survival function from various continuous and discrete distributions. For more information, see the 'SDF Function' on page 817.
