Additional Times Series Data

I've uploaded a couple of files you can use for time series regression. To load the first dataframe, use:
docsUK<-read.csv("http://www.courseserve.info/files/MaternalMortality-DocsUK.csv")

The dependent variable, Y, is maternal mortality (deaths per 100,000 live births) and the independent variable, X, is number of physicians (per 1,000 population).

To use the second, use:
suicidewages<-read.csv("http://www.courseserve.info/files/Suicide-Wages.csv")

The dependent variable, Y, is number of suicides (per 100,000 population) and the independent variable, X, is annual real wages (in dollars). These data are for the US.
