Computes the logarithm of a left cumulative distribution function

Category: Probability

See: 'CDF Function' on page 418

Syntax

LOGCDF ( '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 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' on page 418.
