Slope returns the slope (the average value change per day) of the linear regression line for the variable (i.e. the m part of the equation y = mx + b).
Slope(VarNum, Coefficient Minimum)
VarNum: Variable Number
Coefficient Minimum: Optional. Sets the minimum acceptable Coefficient of Correlation. If the Coefficient of Correlation is below this value, no forecast value will be calculated. If left blank, the Slope value is always displayed.
Slope(1,0.6) Calculates the slope for variable 1 for the date range of the report. If the Coefficient of Correlation is below .6, no value will be calculated.
