### The F-test and the t-test reject the null hypothesis while the KS test and the Chi-Squared test do not

This is a follow-up question to How can the F-test reject the null hypothesis while the KS test does not?. Let's consider I perform the following tests: Two-sample Kolmogorov-Smirnov test (KS-test), ...

### Where can I find a Kolmogorov-Smirnov critical value table for an F-distribution? [closed]

I have developed an Excel model for a one-sample Kolmogorov-Smirnov test for an F-distribution. I have the K-S test statistic, but no CV to compare it to. If anyone knows of an online table of ...

### Can descriptive statistics of three ordered groups be converted into a correlation?

I know that a one-way ANOVA with two groups can be converted into a Standardized Mean Difference (SMD), that can, in turn, be converted into a Pearson correlation. Anyway, with two group means and ...

### Using ANOVA for model comparison with a different ratio, how does it differ?

When we compare two models with ANOVA then we typically compute an F-score like $$F = \frac{\left(\frac{RSS_1-RSS_2}{p_2-p_1}\right)}{\left(\frac{RSS_2}{n-p_2}\right)}$$ where subscripts refer to the ...

### F test to compare variances. How is ncp calculated to obtain the F distribution under the alt hypothesis?

Recently I needed to do a power analysis for a comparison of variance with a F test. In the past I used the OC curves from Edwin Crow's "Statistics Manual" Chart VIII to get beta. https://...

### How to calculate F-statistic given only coefficient, standard errors and confidence intervals in R [closed]

My output is a table of coefficients, together with standard errors and 90 % confidence intervals, nothing else. I miss the degrees of freedom but I do have the number of observations. How can I ...

### F-test for multiple directional alternative hypotheses?

Suppose we have the linear model for Y, with X1, X2 and X3 being continuous independent variables: Y = b0 + b1 * X1 + b2 * X2 + b3 * X3 + e To test H0: b1=b2=0 against H1: b1 or b2 or both are ...

### Notations in the statistical analysis of experimental research

I am very new to experimental setup and have recently started to learn about designing experiments and analyzing the results. In the papers that I read there are notations that I am unfamiliar with. I ...
