About this calculator

Enter your values for the independent variables x_i and the dependent variable y below (leave the last column blank -- this will show the values predicted by the regression model). Arithmetic expressions such as 2/3 or 3+(4*pi) are fine.

You need not use all the columns; for example, if you have two independent variables, then use only x₁, x₂, and y.

When done, press the " y = a + b(x1) + c(x2) + d(x3) + e(x4) " button.

Note The number of data points should be at least one more than the number of independent variables you use. For instance, if you are using two independent variables (x₁ and x₂), you should enter at lesat 3 data points.

Accuracy The algorithm is written to round all output to five significant digits. Further, all numbers of magnitude less that 10^-12 are presented as zero.
