EECS 451 1-SIDED Z-TRANSFORM ∞ DEF: Z + {x(n)} = X + (z) = n=0 x(n)z −n , even if x(n) is noncausal. ∞ Compare to 2-sided z-transform: X(z) = n=−∞ x(n)z −n . WHY?: To solve difference equations with nonzero initial conditions. PROPERTIES OF 1-SIDED Z-TRANSFORM X + (z): 1. x(n) causal→1-sided z-transform X + (z)=2-sided z-transform X(z) 2. Unique inverse only for causal signals: no info on {x(n), n < 0} Equal causal parts but unequal anticausal parts→same X + (z) 3. ROC: Always |z| > |pmax |

Statement Example 1 In this example of thesis statement, the emphasis of the study is to find a correlation, either positive or negative, between Mozart’s music and short term memory. This is an example of a research paper with data observation and analysis. The observations were recorded by running ANOVA and Post Hoc tests to compute values for the variables. The goal was to find a positive correlation between the two variables. For that a hypothesis was tested that was proven to be negative. Alternatively

1 a) It is necessary to use IV to analyze MDVE because it eliminates selection bias. It allows us to capture the causal effect of treatment on the treated in spite of the nonrandom compliance decisions made by participants in experiments. b) Compliers – Assigned to arrest treatment, and delivered the arrest treatment Always Takers – Assigned to a coddle treatment, and delivered the coddle treatment Never Takers – Assigned to coddle treatment, and delivered the arrest treatment Defiers – Assigned

Correlation is a method of testing relationships between quantitative variables or categorical variables. Therefore, correlation is a measure of how things are related. Furthermore, correlation is one of the most useful and most statistics. Correlation can tell whether the relationship between variables is positive or negative. Also, correlation can tell about the strength of relationships. Correlation in statistics can be quantified and assigned a number where zero is “no correlation” and 1 is “perfect

Meaning it is to tell if the correlation between the variables show a positive trend and are STRONG or show a negative trend and are WEAK and the other wary around. An Example of when
