Polynomial Regression Trendline

Hi all,

 

Is it possible to generate a polynomial regression trendline of degree two in Power BI similar to Excel using the LINEST function? I'm expecting two slope values and a coefficient as a result to calculate the trendline equation (y = slope1 * x^2 + slope2 * x + coefficient).

 

Thanks in Advance,

Power BI has introduced LINEST and LINESTX functions. I think you can use these functions to perform polynomial regression as well.
