I think the biggest changes come when there is a whip-saw, such as in a sharp V-shaped recovery from a deep recession. That's what happened in the 50's.<br /><br />Jazzbumpahttps://www.blogger.com/profile/07337490817307473659noreply@blogger.comtag:blogger.com,1999:blog-4290163255778893789.post-1992820813399937342013-07-02T00:00:38.512-04:002013-07-02T00:00:38.512-04:00So, a constant growth rate would have a zero std d...So, a constant growth rate would have a zero std dev. The greater the change in growth rate, the greater the std dev.

Data points perfectly aligned along a straight horizontal line would have a Std DEv of 0. The calculation is complex, but Excel has a function that does it for you.<br /><br />Bigger Std Dev means more spread in the data. <br /><br />It is related to the growth rate of GDP, but not in a simple way.<br /><br />That's what i'm exploring in this post, and I hope I haven't made it too confusing.<br /><br />Cheers!<br />JzBJazzbumpahttps://www.blogger.com/profile/07337490817307473659noreply@blogger.comtag:blogger.com,1999:blog-4290163255778893789.post-21451181879540855692013-07-01T18:33:39.972-04:002013-07-01T18:33:39.972-04:00I am not sure i understand the significance of the...I am not sure i understand the significance of the standard deviation. Is it a measure of the stability of the GDP? Is it relatd to the growth rate of the GDP?Jerry Critterhttps://www.blogger.com/profile/01870618647449723147noreply@blogger.com
