Syntax

LOGCDF('dist',quantile<,parm-1,...,parm-k>)

Arguments

'dist'

is a character constant, variable, or expression 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. [cautionend]

quantile

is a numeric variable, constant, or expression that specifies the value of a random variable.

parm-1,...,parm-k

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

The LOGCDF function computes the logarithm of a left cumulative distribution function (logarithm of the left side) from various continuous and discrete distributions. For more information, see the CDF Function.
