Hi,
I'm having trouble using the PrincipalComponents function in Mathematica v3. I have spatially distributed pressure data over a number of time periods. At each grid point x,y I have a pressure value. I have a full set of pressure readings over a period of time.
So the input data looks like:
{{day1},{day2},...,{dayM}}
where dayN is a list of pressure readings.
PrincipalComponent doesn't work with this data format. What format does the data have to be in? The only format I've been able to get PrincipalComponents to work with is dummy data of the form {{x,y},{x2,y2},{x3,y3}...}, but my data is not in this form.
I hope this makes sense.
