Estimate Probability Vectors From Count Vectors

This function takes a numeric count vector and returns estimated probabilities of the corresponding counts.

The following probability estimation methods are implemented in this function:

• method = "empirical" : generates the relative frequency of the data x/sum(x).

estimate.probability(x, method = "empirical")

Arguments

x

a numeric vector storing count values.

method

a character string specifying the estimation method tht should be used to estimate probabilities from input counts.

Value

a numeric probability vector.

Examples

# generate a count vector
x <- runif(100)
# generate a probability vector from corresponding counts
x.prob <- estimate.probability(x, method = 'empirical')
