We can see, in order, the coefficients for the Year (0.28), the GDP (3.29*10^-4), the Population(-1.94*10^-9)and finally the intercept (-494.6). =XLSTAT_Linest(A2:A2263,B2:D2263,2), all missing arguments being set to their default values.Īfter you click OK or Enter, the regression coefficients along with the intercept are displayed. We wish to display the regression coefficients so we have to enter 2 in the resultType field.Īlternatively, we can enter a formula in an Excel cell as follows: Select Life Expectancy (column A) as the variable to explain (Y) and the Year, GDP and Population (columns B, C and D) as the explanatory variables (X), without selecting the column headers. Finally, select the XLSTAT_Linest function. To use an XLSTAT function, simply type “=” followed by the name of the function or use the Insert / Function menu of Excel, and choose XLSTAT from the drop-down menu. We’ll then compare XLSTAT’s and Excel’s LINEST functions. We will try to predict life expectancy based on the year, GDP and population.
The following example uses a dataset coming from and contains socio demographic variables. Fitting a regression using the XLSTAT_Linest function Other arguments such as the presence of an intercept (true by default), the observations to predict (last one by default) and the observation weights (1 by default) can be selected. The type of results to display (predictions, goodness of fit statistics or regression coefficients) This function takes several arguments, the most important ones being:

In order to illustrate the use of an XLSTAT function within an Excel sheet, we suggest an example that shows how to set up and launch a linear regression with XLSTAT_Linest. How to use XLSTAT functions within Excel cells These functions enable you to estimate probability distribution functions: XLSTAT_PDFArcsineG, XLSTAT_PDFBernoulli, XLSTAT_PDFbeta, XLSTAT_PDFBinomial, XLSTAT_PDFExponential, XLSTAT_PDFLogistic and more. Probability density functions (32 functions) These functions enable you to estimate the inverse cumulative distribution functions of the functions above: XLSTAT_InvCDFArcsineG, XLSTAT_InvCDFBernoulli, XLSTAT_InvCDFbeta, XLSTAT_InvCDFBinomial, XLSTAT_InvCDFExponential, XLSTAT_InvCDFLogistic and more.ħ. Inverse distribution functions (29 functions)
These functions enable you to estimate a cumulative distribution function directly from the formula bar: XLSTAT_CDFArcsineG, XLSTAT_CDFBernoulli, XLSTAT_CDFbeta, XLSTAT_CDFBinomial, XLSTAT_CDFExponential, XLSTAT_CDFLogistic and more.Ħ. Cumulative distribution functions (31 functions)
These functions enable you to perform matrix operations directly in XLSTAT: XLSTAT_MDeterminant, XLSTAT_MInverseX, XLSTAT_MProduct_XY, XLSTAT_MProduct_XtrXĥ. These functions enable you to describe your data in a univariate, bivariate or multivariate way: XLSTAT_Biserial, XLSTAT_Centile, XLSTAT_Covar, XLSTAT_Correl, XLSTAT_FisherExact and more. XLSTAT_ARIMA, XLSTAT_ARIMA2, XLSTAT_ExpoSmooth, XLSTAT_ExpoSmooth2, XLSTAT_Garch, XLSTAT_HoltWinters and more. These functions enable you to study trends and stationarity in time series: XLSTAT_DataSim, XLSTAT_EmpiricalCDF, XLSTAT_GetRank, XLSTAT_Linest, XLSTAT_Logistic, XLSTAT_MannWhitneyTest, XLSTAT_Proportion_CI and more. These functions enable you to run 13 statistical tests on your data directly from the formula bar in Excel. The XLSTAT functions cover 7 main themes: To access these functions, open the Insert Function window in Excel and select the XLSTAT category:

An exhaustive list along with a description of each function is accessible in this PDF document.Īmong the XLSTAT functions that are currently available, some of them solve numerical issues that have been found with the built-in Excel functions, or complement the set of Excel statistical functions. Over 130 XLSTAT functions are available covering 7 main themes. This allows you to benefit from XLSTAT algorithms while linking Excel cells and performing simple or complex Excel operations. On top of user-friendly dialog boxes, XLSTAT offers the possibility to instantly launch a wide range of analyses using simple functions within an Excel spreadsheet.
