LOGPDF Function


Computes the logarithm of a probability density (mass) function

Category: Probability

Alias: LOGPMF

See: 'PDF Function' on page 695

Syntax

LOGPDF ( '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 LOGPDF function computes the logarithm of the probability density (mass) function from various continuous and discrete distributions. For more information, see the 'PDF Function' on page 695.
