Regresión lineal
- Sumatoria de “x”
∑X = 324.365+ 569.785+ 731.114+ 815.291+ 867.614+ 913.346+ 948.3333+ 1
∑X = 5169.85
- Sumatoria de “y”
∑Y = 42125.2706+ 38498.9829+ 34165.70041+ 29554.2636+ 26054.4882+ 23600.6635+ 21651.4460
∑Y = 215650.8189
- Sumatoria de “XY” (X1 Y1 + X2 Y2….)
∑XY = (324.365 x 42125.2700)…
∑XY = 149368047.1517 ∑X2 = 4115385.143
Pendiente:
