Across
- 4. calculated by dividing MSR (mean squared regression) by MSE (mean squared error), or explained variance by unexplained variance
- 7. Having or having to do with a single variable
- 10. a family of curves indexed by a parameter called the degrees of freedom, which can take the values 1, 2, …
- 11. a measure of the joint variation between variables
- 13. The difference between a datum and the value predicted for it by a model
- 14. error occurs if the null hypothesis is not rejected when it is in fact false
- 15. error occurs when the null hypothesis is rejected erroneously when it is in fact true
- 16. A "dummy" treatment that has no pharmacological effect
- 17. calculations that provide information about levels of variability within a regression model and form a basis
- 18. tests of significance
Down
- 1. A time series where underlying generating process does not have a constant mean and/or a constant variance
- 2. a sample where subsets of sampling units are selected separately from different strata, rather than from the frame as a whole
- 3. the smallest significance level for which any of the tests would have rejected the null hypothesis
- 5. A distribution that is not symmetrical
- 6. What is true for the parts is not necessarily true for the whole
- 8. Having exactly one mode
- 9. indicates how much of the dependent variable’s total variation is accounted for by the predictor variable
- 12. An hypothesis test based on approximating the probability histogram of the Z statistic under the null hypothesis by the normal curve
