You've Got a Trend

Lyrics © 2017 Dennis K. Pearl and Lawrence M. Lesser
may sing to the tune of  "You've Got a Friend" by Carole King

When your pattern is muddled
and just how the data spans
and nothing, nothing flows just right.
Close your eyes and think curvy lines
and soon it will be there
to brighten up data with ev’ry byte.

You just call a pattern by name
and you know whenever it can,
the series is running, oh yeah baby, to add points again.
Winter, spring, summer or fall,
seasonality is the call.
It’ll be there, yeah, yeah, yeah
You've got a trend.

If the points above your line
should be randomly spread out,
and give that old balance with those below;
keep their fit together
and see my line in the cloud now.
Soon you'll see the errors you don’t ignore.

You just call a pattern by name
and you know whenever it can,
the series is running, oh yes it will, to add points again.
Winter, spring, summer or fall, yeah
seasonality is the call.
It'll be there, yes it will.

Ain't it good to know that you've got a trend.
When data are uncontrolled
they'll spurt you, and avert you
and take control if you let them.
Oh yeah, don't you let 'em now.

You just call a pattern by name
and you know whenever it can,
the series is running, oh yes it will, to add points again.
Winter, spring, summer or fall, yeah
seasonality is the call.
It'll be there, yes it will.
You’ve got a trend.

You've got a trend, yeah.
Ain't it good to know you've got a trend.
It’s cyclical, so I’ll say it again:
Oh, yeah yeah, you've got a trend.
