... in each box are computed so that the side-by-side boxes have nonoverlapping notches when their medians are different at a default 5% significance level. The computation is based on an assumption of normality in the data, but the comparison is reasonably robust for other distributions. The side-by-si ...

Quantitative Statistics: Chi
... Chi-Square (X2) is a statistical test used to determine whether your experimentally observed results are consistent with your hypothesis. Test statistics measure the agreement between actual counts and expected counts assuming the null hypothesis. It is a non-parametric test. The chi-square test of ...

... We will use the notation y R x for the linear regression straight line equation. Like any straight line it is defined by two parameters; here R is the value of y when x = 0 (called the intercept on the y axis) and is the slope of the line. Note 1: the use of the R subscript for alpha (the ...

... The Chi Square test is known as the “goodness to fit” test because it is the sum of the squared value between the observed results and the expected results divided by the expected value. The results of this are charted and compared to determine the deviation from the expected normal values. The diff ...

Applying bootstrap methods to time series and regression models
... • Advantage of moving blocks approach: doesn’t depend on a specific model. • Note: we still use an AR model in this framework as we apply it on each bootstrap sample. The difference is that we don’t use it to generate the bootstrap sample! • disadvantage of moving blocks approach: How to choose a bl ...
