A new menu appears. Note that cell range E8:E108 contains the stock returns and the cell range F8:F108 contains the index returns Beta Calculation There are two ways of calculating beta with Excel – the first uses the variance and covariance functions, while the second uses the slope function. Solve Cubic Equation in Excel using Solver. TREND Function Description: The TREND Function Calculates Y values based on a trendline for given X values. Before you create a trendline: You can add trendlines to bar, line, column, or scatter charts. When you add a trendline to a chart, Excel provides an option to display the trendline equation in the chart. Normally, Excel will change cell references when you insert or delete rows or columns, even when you use absolute referencing. What I have is a graph which can be approximated by a polynominal formula. The line and fitted equation will. Notice the address of this cell appears to complete the equation in both locations (1), and cell C3 itself is highlighted (2). Select the first value of the new trendline and copy the function by using Excel's Auto Fill feature, dragging the fill handle in the cell's lower right corner to the right until the cell of the last value is selected as well. Add the equation to the trendline and you have everything you need. This graph must be properly labeled, include a trendline, and have the trendline equation displayed on the graph along with the R2 value. The formula is the intercept in F2 plus the slope in E2 times this row's month number. Using the previous example, this gives the approximate equation for the tangent line as "y = 0.
