This is a toy (i.e. "fake") data set created by the `fabricatr`

package.
There are 100 observations. The outcome `y`

is a linear function
of `20 + (.25 * year) + .(25 * x1) + (1 * x2) + e`

. This clearly implies
some autocorrelation in the data. I.e. it's a time-series.

`fakeTSD`

A data frame with 100 observations on the following 5 variables.

`year`

the year

`y`

an outcome

`x1`

a continuous variable

`x2`

a binary variable

`e`

randomly generated errors

Errors are random-normal with a mean of 0 and a standard deviation of 1.
`x1`

is generated by a normal distribution with a mean of 5 and a standard
deviation of 2. `x2`

is drawn from a Bernoulli distribution with a
probability of .5 of observing a 1.
