Standard error of the mean

[luka.peternel@mf.uni-lj.si]

Hi flex pro users,

I would like to present on the chart three signals as the mean value + standard error of the mean. I was able to create the mean value, however, I have difficulties with the standard error. Do you have any idea how to do this.

Thanks

You can use the [b]Statistical Characteristic Quantity Analysis Object[/b] to calculate different statistical characteristic quantities for a data set or you can create a FPScript formula to calculate the variance:

[code]NumberOfValues(Signal) / (NumberOfValues(Signal) – 1.L) * (Mean(Signal ** 2.L, PROCESS_COLUMNS) – Mean(Signal, PROCESS_COLUMNS) ** 2.L)
[/code]
