Calculating the slope of a best fit line
WebIn order to fit a least-squares regression line. And let's say the least-squares regression line looks something like this. And a least-squares regression line comes from trying to minimize the square distance between the line and all of these points. And then this is giving us information on that least-squares regression line. WebThe vertical axis of the plot is in dB. The different RT60 measures (e.g. T20, T30, REW’s Topt) are derived by calculating the slope of a best fit line to the Schroeder curve over different ranges (detailed below). In a diffuse field the curve with the dB vertical scale is quite linear until it reaches the noise floor.
