And with a little guidance, users can employ more advanced statistical methods with Excel. I am good on this part. I have a column with intervals(every 30 min) and with some values. This seems like something simple on the surface, but apparently it's not. If you want to calculate the value of this function at x = 1, this can be done with the Excel Weibull function, as follows: The above chart on the right shows the Weibull Cumulative Distribution Function with the shape parameter, alpha set to 5 and the scale parameter, beta set to 1.5. I have to do it 891 times. I SEE A HELPFUL EXCEL UASGE AND HERE BELOW ONE QUESTION. I am trying to work out how to calculate the geometric mean of a series of values, some of which are negative, ie.
