Linear Regression Analysis
hi,
That is the formula, usually Y = ax +b where a is the slope and b is the y intercept. In Excel you can use the =LINEST function to calculate various regression parameters, you can use the TREND function to esimate a new y value based on a given X. You can use the SLOPE function to find the slope of the linear regression line for a series of point pairs, you can use the INTERCEPT function to find the intercept of the same series. You can plot the data in a chart and then ask Excel to plot a Linear trendline and display the formula on the chart. Or you can use the Data Analysis command's Regression tool to present a myrid of regression statisticsl. -- Thanks, Shane Devenshire "Dana" wrote: What is the formula for linear regression where Y = B(X) + C? -- Dana |
