WebJun 11, 2024 · interpolate() — interpolating. If we want to mean interpolate the missing values, we need to do this in two steps. First, we generate the underlying data grid by using mean(). This generates the grid with NaNs as values. Afterwards, we fill the NaNs with interpolated values by calling the interpolate() method on the read value column: WebOct 30, 2024 · Interpolation – Linear. It’s the method of approximating a missing value by joining dots in increasing order along a straight line. In a nutshell, it calculates the unknown value in the same ascending order as the values that came before it. Because Linear Interpolation is the default method, we didn’t have to specify it while utilizing it.
