Linear Regression


I've got a table like this


year    Sales

2012  10

2013  12

2014  13

2015  13

2016  16

2017  15

2018  17

In can put this in to a Line Chart Visual and a Trend Line. This will show me the Sales Trend. I want to find the slop of the trend line by using a linear regression in DAX. How do I do that?
It's very simple in Excel

Hello @Torbenan 

Take a look at this excellent post by Daniil Maslyuk.


Thank - that seems to be the way to go. Just wonder, why this i so simple in Excel (=LINREGR(B3:B9;A3:A9)) and so complicated in Power Bi


Because Excel is 25 years older than DAX. Smiley Happy  They add new features every month so you may see something like LINREGX(table,expression) in the future.
