Gradient of regression calculator
WebFeb 13, 2024 · Here we show you how the exponential regression formula can be derived. To determine the coefficients a and b, follow these steps: Take the logarithm of both sides of the equation; we have the following equivalent equation: ln (y) = ln (a × bˣ). The properties of logarithms give: ln (y) = ln (a) + ln (bˣ) and ln (y) = ln (a) + x × ln (b). WebOur aim is to calculate the values m (slope) and b (y-intercept) in the equation of a line : y = mx + b Where: y = how far up x = how far along m = Slope or Gradient (how steep the line is) b = the Y Intercept (where the …
