Computes the logarithm of a probability density (mass) function
Category: Probability
Alias: LOGPMF
See: 'PDF Function' on page 695
LOGPDF ( 'dist',quantile,parm-1, ,parm-k )
'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.
