Life expectancy at birth from 1960 to 2017
Description
The data is available by the courtesy of the World Bank under Creative Commons Attribution 4.0 (CC-BY 4.0). It includes the life expectancy at birth on nation level from 1960 to 2017. The data has been converted to long data format, aggregates for groups of nations and missings have been deleted and a grouping variable with a broader scope spanning 4 years each has been added. It shows, that it can be better to reduce predictors. The model does not converge anymore after using 8 predictors and the optimal solution is achieved with four predictors, equaling R2=.9825.
Usage
life
Format
A data frame with 11182 rows and 4 variables:
- Country
The name of the country
- year
reference year of data collection
- life
the life expectancy at birth
- group
a grouping variable based on 'year' but with a lower resolution; spans intervals of 4 years each
A data frame with 11182 rows and 4 columns

Examples
## Not run:
# data preparation
data.life <- rankByGroup(life, raw="life")
data.life <- computePowers(data.life, age="year")
#determining best suiting model by plotting series
model.life <- bestModel(data.life, raw="life")
plotPercentileSeries(data.life, model.life, end=10)
# model with four predictors seems to work best
model2.life <- bestModel(data.life, raw="life", terms=4)
