About this calculatorEnter 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 x_{1}, x_{2}, 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 (x_{1} and x_{2}), 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. |
