WebTips: If you want, you can apply the criteria to one range and sum the corresponding values in a different range. For example, the formula =SUMIF(B2:B5, "John", C2:C5) sums only the values in the range C2:C5, where the corresponding cells in the range B2:B5 equal "John.". To sum cells based on multiple criteria, see SUMIFS function. Web8.1 Introducción. LOWESS (suavizado de dispersión de ponderación local), a veces llamado LOESS (suavizado de ponderación local), es una herramienta popular que se utiliza en el análisis de regresión que crea una línea suave a través de una gráfica de distribución o de dispersión de tiempo para ayudar a ver la relación entre variables y prever tendencias.
