Hi Guys, I am trying to specify a polynomial regression function which best matches a trend of data, to forecast future data. The function is mainly for calculating statistics for a specific line, and it uses a method known as “least squares” when calculating the straight line that will perfectly fits the inputted data, and then it would return with the array that successfully describe =LINEST(A2:A15, B2:B15, TRUE, TRUE) The output from the LINEST function contains the coefficients of the regression model along with several additional statistics: The following screenshot provides an explanation of each value in the output: From the output we can see: The coefficient for β 0 is 3. dev. and so on =INDEX(LINEST(D1:D5,A1:C5),1) gives the first coefficient for a 3rd order polynomial fit to the data in column D. But what I thought was the best approach was to use VBA to copy over the arrays but deleting the ones with blank values. This function uses the following basic syntax: = LINEST (known_y's, [known_x's], [const], [stats]) where: known_y’s: An array of known y-values; known_x’s: An array of known x-values; const: Optional argument. Is there a way to have Linest return the coefficient and intercept in the same column? (i. Is there a way/formula to select/filter the datainput to Linest based on the product without using VBA?
