Returns the logarithm of a left cumulative distribution function.
LOGCDF('dist',quantile<,parm-1,...,parm-k>)

-
'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]](../../../../common/63294/HTML/default/images/cautend.gif)
-
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.
