LOGCDF Function

Returns the logarithm of a left cumulative distribution function.

Category:	Probability
See:	CDF Function

Syntax

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

Required 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'`
Generalized Poisson	`'GENPOISSON'`
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'`
Tweedie	`'TWEEDIE'`
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 variable, constant, or expression that specifies the value of a random variable.

Optional Argument

parm-1,...,parm-k

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

Details

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.
