The OVER function is a very useful function in Spotfire that calculates expressions and aggregations across different groups of data. I’ve previously written about the OVER function, which you can check out here. This post has additional examples using the OVER function, focusing on multiple columns and expressions requiring the Intersect function.
There are many different ways to use standard deviation in TIBCO Spotfire – the video in this post shows 6 different examples of how you can use standard deviation in Spotfire to learn more about your data.
Standard deviation is a statistical calculation that’s used to describe the spread of data around its average value. Standard deviation is simply the square root of the data’s variance, and the variance describes how close each data point is to the overall average. Standard deviation is useful in when analyzing the distribution a dataset, as shown in the screenshot below.
