Simple Random (sampling type) - Answer- Every member of the population has an equal chance of being selected -it's simple and it's random. Systematic (sampling type) - Answer- Every kth member of the population is selected for the sample. It's easy to do manually, but there can be periodicity which allows for bias. Stratified (sampling type) - Answer- Divide the population into mutually exclusivegroups based on one variable (strata). Next, randomly and proportionally select from those s...

Linear Discriminant Analysis (LDA) Questions & Accurate answers, VERIFIED. Why do we need another method from logistic regression? - LDA does not suffer from the problem of when the classes are separated, the parameter estimates for the logistic regression are surprisingly unstable. Also if n is small and the distribution of the predictors X is approximately normal in each of the classes, the LDA is more stable. Thirdly, LDA is popular when we have more than two response classes. Prior p...
