Hello, I have a file with multiple rows (4) for each subject, each row with a var value for a particular data point. I want to create a set of individual 'spaghetti' graphs mapping these 4 values for each subject. Any suggestions how I can do it in SPSS or where should I look for instructions? Thanks so much.

Subject: Re: Significance testing between R-square from linear and R-square from curvilinear regression (Revised).
Hi:
Steiger's homepage:
http://www.unav.es/genetica/new/soft.html#miscAnd Multicorr page:
http://www.interchange.ubc.ca/steiger/multi.htmAnyway, the links in this page are wrong (they point to a
nonexisting ftp site). I found out that the correct links for
multicorr program & documentation are:
- Program:

SPR> Steiger's multicor program will do that.

SPR> Subject: Significance testing between R-square from linear and R-square
SPR> from curvilinear regression (Revised).
SPR> Hi, I want to clarify my question in previous question.
SPR> I have two variables, X: time (11 time points) and Y: means of
SPR> evaluation (one group, N = 132).
SPR> I expect that exponential function will fit better than a linear
SPR> function to predict the trajectory.
SPR> I did a curve estimation with exponential function and found R-square
SPR> from the exponential function is greater than R-square from a linear
SPR> function.
SPR> But how can I test if the difference in R-squares is signifcant?
SPR> I found a formular in Blalock (1972). But it requires correlation
SPR> between Y and transformed Y.
SPR> Should I do time series analysis?
SPR> Any help will be greately appreciated. Thanks in advance,
