pdf.Geometric {distributions3} R Documentation

## Evaluate the probability mass function of a Geometric distribution

### Description

Please see the documentation of Geometric() for some properties of the Geometric distribution, as well as extensive examples showing to how calculate p-values and confidence intervals.

### Usage

## S3 method for class 'Geometric'
pdf(d, x, drop = TRUE, elementwise = NULL, ...)

## S3 method for class 'Geometric'
log_pdf(d, x, drop = TRUE, elementwise = NULL, ...)


### Arguments

 d A Geometric object created by a call to Geometric(). x A vector of elements whose probabilities you would like to determine given the distribution d. drop logical. Should the result be simplified to a vector if possible? elementwise logical. Should each distribution in d be evaluated at all elements of x (elementwise = FALSE, yielding a matrix)? Or, if d and x have the same length, should the evaluation be done element by element (elementwise = TRUE, yielding a vector)? The default of NULL means that elementwise = TRUE is used if the lengths match and otherwise elementwise = FALSE is used. ... Arguments to be passed to dgeom. Unevaluated arguments will generate a warning to catch mispellings or other possible errors.

### Value

In case of a single distribution object, either a numeric vector of length probs (if drop = TRUE, default) or a matrix with length(x) columns (if drop = FALSE). In case of a vectorized distribution object, a matrix with length(x) columns containing all possible combinations.

Other Geometric distribution: cdf.Geometric(), quantile.Geometric(), random.Geometric()

### Examples


set.seed(27)

X <- Geometric(0.3)
X

random(X, 10)

pdf(X, 2)
log_pdf(X, 2)

cdf(X, 4)
quantile(X, 0.7)
