Hi Group,
This is a little difficult to explain, but the underlying data is simple, so
please bear with me. I have Dates and Closings for the Dow Jones Industrial.
Similar to below:
Date Adj. Close*
01/03/05 10729.43
12/27/04 10776.13
12/20/04 10661.6
12/13/04 10638.32
.............More Data

The above is easy to graph and I have automated the process, which includes
a 6th Order Polynomial Trend line added to the graph. What I am trying to do
is find the Data Points associated with the 6th Order Polynomial Trend line.
It has simply been just too long since I have done this type of statistics. I
believe it may be necessary to create a new table to find these data points,
which I am willing to do. I can calculate the sample mean, number of sample
variables, sample variance, sample standard deviation, etc., but it has just
been too many years to bring the necessary statistical expertise to arrive at
the data points. I am trying to get a table that looks something like this:
Date Adj. Close* Trend
01/03/05 10729.43 10730.25
12/27/04 10776.13 10750.31
12/20/04 10661.6 10765.03
12/13/04 10638.32 10750.00
I have tried using some of the built in functions, but they do not yield the
same data points that have been graphed by the 6th Order Polynomial Trend
line. I have tried Trend and Forecast. I created a table many years ago,
which I think calculated the data points, but it has simply been to many
years and I have lost the statistical expertise. Any help would be greatly
appreciated. I have used the equation that can be presented with the graph,
but it also does not yield the Data Points associated with each Date and Adj
Close.
Thanks in advance.
