WebThe square root of the mean square residual can be thought of as the pooled standard deviation. The F ratio is the ratio of two mean square values. If the null hypothesis is true, you expect F to have a value close to 1.0 most of the time. A large F ratio means that the variation among group means is more than you'd expect to see by chance. Web31 Jul 2015 · I don't understand the question, if there even is one. You resize them to make the sizes match and then you call the built-in immse() function. What you get is what you get. If you used binlinear interpolation, you get the MSE for bilinearly interpolated images. If you used cubic interpolation, then you get the MSE for cubic interpolated images. WebThe square of a standard normal random variable has a chi-squared distribution with one degree of freedom. If X is a Student’s t random variable with ν degree of freedom, then X 2 is an F (1,ν) random variable. If X is a double exponential random variable with mean 0 and scale λ, then X is an exponential random variable with mean λ. buddy the cat story
