Using a Random Forest model with this feature as an input, we managed to achieve MAE of11.4mins. This means that our model produces an error of 11.4 minutes on average when trying to predict OPT on unseen data, which corresponds to a MAPE of 0.34. This result is valid in our case. In...
How do you compute the mean for a frequency table? Define epidemiology, risk ratio, and odds ratio. What is a proportion and how is it computed? Explain what is the difference between Math 222 and Statistic 222. Explain how to interpret the expected value. ...
One could compute Cronbach Coefficient Alpha, Kuder Richardson (KR) Formula, or Spilt-half Reliability Coefficient to examine internal consistency within a single test. Cronbach Alpha is recommended over the other two for the following reasons: 1. Cronbach Alpha can be used for both binary-type ...
Suppose you are given a particular set of data and found that r = -.78. How would you interpret this result? Coefficient of correlation: The value of r is the coefficient of correlation. This always lies between -1 and +1(−1≤r≤1)for data t...
Can correlation ever imply causation or do we always have to look at them separately? Explain how to create correlated random variables. What is the coefficient of determination? Why is it important to know the amount of shared variance when interpreting the ...
The average of all initial morning alertness ratings logged by participants within the first three hours after the start of the standardised breakfast meal was used to compute a daily morning alertness score for each participant (Fig. 2c, d). This time period was defined within the experimental...

How can you determine the degrees of freedom by looking at the sample size on SPSS output? How do I compute an ANOVA summary table with this data? Is there enough evidence to reject the null hypothesis? How do I compute an F-statistic with this data and evaluate F on k-1 ...
In this work we investigate the role of condensates on the expectation value of the Polyakov loop. The Polyakov loop is closely related to the thermal expectation value of tr(A2 0 ) (the NLO perturb...K. Kajantie, M. Laine, K. Rummukainen and Y. Schro¨der, How to resum long-...
