Test of normality - Samenvattingen, Aantekeningen en Examens

Using MLE, can we derive estimated coefficients/parameters in exact form? - No, they are approximate estimated parameters T/F: The sampling distribution of the predicted response variable used in statistical inference is normal in multiple linear regression under the normality assumption. - F Classification - The prediction of binary responses. Classification is nothing more than a prediction of the class of your response, y* (y star), given the predictor variable, x* (x star). If the predi...

Bonferroni-Holm Multiple Comparisons : -In the context of an ANOVA, rejecting the null hypothesis means there is a statistical difference between at least two means, but it won't tell you where it is. You use this to discover exactly which means are different. -Only used for Model I ANOVAs -A t-statistic for a two sample t-test assuming equal variance Steps to Applying the Bonferroni-Holm Multiple Comparison Test : Step 1: Calculate test statistics and corresponding P values for each ...

The prediction interval of one member of the population will always be larger than the confidence interval of the mean response for all members of the population when using the same predicting values. - true See 1.7 Regression Line: Estimation & Prediction Examples "Just to wrap up the comparison, the confidence intervals under estimation are narrower than the prediction intervals because the prediction intervals have additional variance from the variation of a new measurement." In ANOV...
