What does the Linest function tell you?

The LINEST function calculates the statistics for a straight line that explains the relationship between the independent variable and one or more dependent variables, and returns an array describing the line. The function uses the least squares method to find the best fit for your data.

Does Linest work for any function?

The Microsoft Excel LINEST function uses the least squares method to calculate the statistics for a straight line and returns an array describing that line. The LINEST function is a built-in function in Excel that is categorized as a Statistical Function. It can be used as a worksheet function (WS) in Excel.

What is Linest function error?

If the x-value and y-value ranges overlap, the LINEST worksheet function produces incorrect values in all result cells. Normal statistical probability disallows the values in the x and y ranges to overlap (duplicate each other). You can use the Regression tool instead of the LINEST worksheet function.

What does r2 measure in a regression model?

R-squared (R2) is a statistical measure that represents the proportion of the variance for a dependent variable that’s explained by an independent variable or variables in a regression model. It may also be known as the coefficient of determination.

Does a negative correlation mean it is weak?

A negative correlation can indicate a strong relationship or a weak relationship. Many people think that a correlation of –1 indicates no relationship. But the opposite is true. The minus sign simply indicates that the line slopes downwards, and it is a negative relationship.

What does a correlation test tell you?

Correlation is a statistical technique that can show whether and how strongly pairs of variables are related. For example, height and weight are related; taller people tend to be heavier than shorter people. Correlation can tell you just how much of the variation in peoples’ weights is related to their heights.
