Hi How would I analyse time series with - different lengths (i.e. one has 9 entries and the other has 14 entries) - different frequency (i.e. dates are random - no repeated length) - multiple values for the same time entry (e.g. 2009-10-23 below) i.e. my data takes the form: 1st time series 2009-10-07 0.009378 2009-10-19 0.014790 2009-10-23 -0.005946 2009-10-23 0.009096 2009-11-08 0.004189 2009-11-10 -0.004592 2009-11-17 0.009397 2009-11-24 0.003411 2009-12-02 0.003300 2010-01-15 0.010873 2010-01-20 0.010712 2010-01-20 0.022237 2nd time series 2009-09-23 0.076253 2009-10-07 0.039255 2010-02-17 0.039045 2010-03-09 0.024201 2010-03-25 -0.039810 2010-04-13 -0.012428 I am unable to get any functions to work. I would very much like to use the function charts.PerformanceSummary... Thanks.
