FlightsDF

FlightsUnits

FlightsIdt

A interval-valued data set containing 142 units and four interval-valued variables (dep_delay, arr_delay, air_time and distance), created from from the flights data set in the R package nycflights13
(on-time data for all flights that departed the JFK, LGA or EWR airports in 2013), after removing all rows with missing observations, and aggregating by month and carrier.

datasets

interval data

Implements methodologies for modelling interval data by Normal
and Skew-Normal distributions, considering appropriate parameterizations of
the variance-covariance matrix that takes into account the intrinsic nature of
interval data, and lead to four different possible configuration structures.
The Skew-Normal parameters can be estimated by maximum likelihood, while Normal
parameters may be estimated by maximum likelihood or robust trimmed maximum
likelihood methods.

nycflights function

FlightsDF: A data frame containing the original 327346 valid (i.e. with non missing values) flights from the nycflights13 package, described by the 4 variables: dep_delay, arr_delay, air_time and distance. 
 FlightsUnits: A factor with 327346 observations and 142 levels, indicating the month by carrier combination to which each orginal flight belongs to. 
 FlightsIdt: An IData object with 142 observations and 4 interval-valued variables, describing the intervals formed by agregating the FlightsDF microdata by the 0.05 and 0.95 quantiles of the subsamples formed by FlightsUnits factor.
