Index linest
I want to write a VBA function making use of LINEST excel function to calculate some tstats for the slope. I know that i have to combine the INDEX function with the LINEST function, but i don't kno =INDEX(LINEST(F17:N17,F16:N16^{1;2;3}),1) The above formula is part of a much longer formula. I want to repace the references with the INDIRECT function but I am getting #REF when I put INDIRECT in as the second argument. Advanced Excel Statistical - LINEST Function - The LINEST function calculates the statistics for a line by using the least squares method to calculate a straight line that best fits your data, and then ret Y-intercept: =INDEX(LINEST(known_y's,known_x's),2) The accuracy of the line calculated by LinEst depends on the degree of scatter in your data. The more linear the data, the more accurate the LinEst model. LinEst uses the method of least squares for determining the best fit for the data. When you have only one independent x-variable, the Didn’t see it mentioned, may be exceedingly obvious, but you can use the index function to extract each of the coefficients the linest function spits out. This way you can have it retrieve a single y value using the trendline values based on a given x value in a single cell, and update the y value if the x changes. eg for a second order poly Steps to use the Linest function in Excel. LINEST function returns several outputs, so to begin, select a 2 by 5 array as shown. Click , the Insert function icon.; In the Insert Function popup menu, choose the Statistical category and then choose the LINEST function. Click OK.; In the Function Arguments window, click the Known y's field and drag your mouse to highlight the y-values. Update 28 June 2015: Also see Using Linest for non-linear curve fitting examples, hints, and warnings for more examples of fitting exponential and polynomial curves using LinEst. A frequent question on internet forums everywhere is how to do a least squares fit of a non-linear trend line to a set of data. The most frequent answer is…

La función ESTIMACIÓN.LINEAL calcula las estadísticas de una línea utilizando el método de los "mínimos cuadrados" para calcular la línea recta LINEST. Given partial data about a linear trend, calculates various parameters about the ideal linear trend using the least-squares method. 39, =INDEX(LINEST(b,a^{1,2,3,4}),2). 40, 1,2,3,4 for Poly 4th order. 41. 42, Coefficient A3. 43, a is the name of the, range of data x-value (here cell C6 to C14). =INDEX(LINEST(ni,rev,1,1),4,2) will find the degrees of freedom. This means we can take one value at a time and enter it as and where we like and we don’t have to stick rigidly to the tabular format that Excel uses with the full LINEST output table. =INDEX(LINEST(known_y's,known_x's),1) Y-intercept: =INDEX(LINEST(known_y's,known_x's),2) The accuracy of the line calculated by the LINEST function depends on the degree of scatter in your data. The more linear the data, the more accurate the LINEST model. LINEST uses the method of least squares for determining the best fit for the data. When I happened to visit your site while I am drafting my web page for a program (finding the best fit regression equation out of 9 equations) and to display the trend line of best fit on X-Y chart) in order to explain Linest function and Index function referring to Linest function's result matrix.
