Webb26 feb. 2024 · My idea is that if the lateral acceleration in a specific point is equal or very close to the average value in the data set (all points in all trajectories), the standard deviation is set to 1 in that point. The standard deviation could e.g. be a staircase function with a constant value for lateral accelerations in a certain interval. Webb19 sep. 2024 · To calculate the variance in a dataset, we first need to find the difference between each individual value and the mean. The variance is the average of the squares of those differences. We can express the variance with the following math expression: σ2 = 1 n n−1 ∑ i=0 (xi − μ)2 σ 2 = 1 n ∑ i = 0 n − 1 ( x i − μ) 2. Webb29 apr. 2024 · Standard deviation is a squared root of the variance to get original values. Low standard deviation indicates data points close to mean.
