LOGPDF Function

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.
