expdat {mixdist}

A Mixture Data of Three Exponential Distributions

Description

A total of 1000 observations was generated by computer to follow the mixture distribution 1/3 E(1) + 1/3 E(4) + 1/3 E(16) where E(m) denotes an exponential distribution with mean m.

The expdat data frame has 25 rows and 2 columns.

Usage

data(expdat)

Format

This data frame contains the following columns:

x

the boundaries of grouping intervals.

freq

the frequencies of observation falling into each interval.
