fitdistr_tidiers: Tidying methods for fitdistr objects from the MASS package

Description

These methods tidies the parameter estimates resulting from an estimation of a univariate distribution's parameters.

Usage

## S3 method for class 'fitdistr':
tidy(x, ...)
## S3 method for class 'fitdistr':
glance(x, ...)

Arguments

x

An object of class "fitdistr"

...

extra arguments (not used)

Value

• All tidying methods return a data.frame without rownames, whose structure depends on the method chosen.

  tidy.fitdistr returns one row for each parameter that was estimated, with columns:

• term
  The term that was estimated
• estimate
  Estimated value
• std.error
  Standard error of estimate
• glance.fitdistr returns a one-row data.frame with the columns
• n
  Number of observations used in estimation
• logLik
  log-likelihood of estimated data
• AIC
  Akaike Information Criterion
• BIC
  Bayesian Information Criterion

Examples

set.seed(2015)
x <- rnorm(100, 5, 2)

library(MASS)
fit <- fitdistr(x, dnorm, list(mean = 3, sd = 1))

tidy(fit)
glance(fit)
