Strike Durations

Description

Data on the duration of strikes in US manufacturing industries, 1968–1976.

Usage

data("StrikeDuration")

Format

A data frame containing 62 observations on 2 variables for the period 1968–1976.

duration
strike duration in days.
uoutput
unanticipated output (a measure of unanticipated aggregate industrial production net of seasonal and trend components).

Details

The original data provided by Kennan (1985) are on a monthly basis, while Greene (2003) only provides the June data for each year. Also, the duration for observation 36 is given as 3 by Greene while Kennan has 2. Here we use Greene's version.

exp(-fit_lnorm$estimate[1])
## Weibull and lognormal distribution have
