The parameter a is the height of your curve's peak, b is the place of the center of the peak, and c (the regular deviation, in some cases known as the Gaussian RMS width) controls the width of the "bell". 由於常態分布含有指數項的特性，超出某個標準差範圍的機率會隨著該範圍的擴大而大幅減小。假如某實驗每天進行一次，則實驗結果超出某標準差範圍的頻率可列為下表： 範圍 It’s not downright unusa... https://www.terpzcannabisflower.com/
