Dist.RT(x, r) 1 chisq.

The coefficient of correlation R ranges between -1 and 1, with 0 showing no correlation, 1 showing perfect correlation and -1 being perfect anti-correlation.

Enter the x and y data (if the x values are always the same and n is always 90 you could put the x values in the template).

The correlation coefficient can be simply calculated in Microsoft Excel.

Many thanks, reply With" :11 AM #2, there is an example of how to use the linest function for polynomial trendlines.dline_formulas, the formulas are used to calculate the coefficients for each term and the constant.Dist(3,4,true) into a cell will output.442175.For each subject.Rename the x, y and Formula ranges by i) selecting cells A1:Cn ii) On the menu bar select Insert/Name/Create and tick Top Row then OK iii) You will then be asked if you want to replace the the existing x, y and Formula values,.R-squared - ranging between 0 and 1 - is often used to report the similarity between two sets of data.Am I to assume that a 4th order poly should not be used even though if I calculate values in excel myself R values are markedly improved?At the moment Im just inuputting each individual data set but taht could take some time.I know R2 values just tell me how close the curve comes to my data points and doesnt necessarily mean the fit is 'good' in other ways.

Also, when using 3rd order poly for my 90 data sets most R2's are.80 but for those individuals that aren't (e.g.

Sorry for the hundreds of questions, any help would be much appreciated!

Reply With" :10 AM #7, the formula used for the linest function is shown in the link to website I mentioned earlier.Statistics is a subject with a number of probability distributions and formulas.The first of these is chisq.For several large sets of data the best thing to do is keep one file as astrid harrewijn miss communicatie epub a sort of template.But to create the 'C' column/value to input in this formula Im not sure how to use the linest function?Change "array 1" and "array 2" to the corresponding ranges of the two sets of data you wish to correlate.
