ISYE 6414 - Midterm 1 Prep (2023/2024) Already Graded A If λ=1 we do not transform non-deterministic Regression analysis is one of the simplest ways we have in statistics to investigate the relationship between two or more variables in a ___ way random The response variable is a ___ variable, because it varies with changes in the predicting variable, or with other changes in the environment fixed The predicting variable is a ___ variable. It is set fixed, before the response is measured. si...

science, lawful relations - Answer- __ is more than the mere description of events as they occur. It is an attempt to discover order, to show that certain events stand in __ to other events (Skinner, 1953, p.6)." evidence - Answer- Being scientifically skeptical means that until there is __ available, assumptions should not be made. bias, evidence, replication - Answer- In order to be excellent stewards of science, as behavior analysts, we can follow a few guidelines when gathering and ev...

Error - Classifying a record as belonging to one class when it belongs to another class Error rate - Percent of misclassified records out of the total records in the validation data 1 - Error Rate - Formula for accuracy Confusion Matrix - Summarizes binary classification error Binary classification error - What type of error does a confusion matrix classify? Prediction (horizontal) and actual (vertical) - What are the two axes in a confusion matrix?

σ^2 (sample distribution of the variance estimator) - is chi-squared distribution with n - 2 degrees of freedom (We lose two degrees of freedom because we replaced the two parameters ß0 and ß1 with their estimators to obtain the residuals.) constant variance assumption - which means that the variance (σ^2) of the error terms or deviances is constant for the given population. A violation of this assumption means that the estimates are not as efficient as they could be in estimating the ...

response (dependent) variables - ANS one particular variable that we are interested in understanding or modeling (y) predicting or explanatory (independent) variables - ANS a set of other variables that might be useful in predicting or modeling the response variable (x1, x2) What kind of variable is a response variable and why? - ANS random, because it varies with changes in the predictor/s along with other random changes. What kind of variable is a predicting variable and why? - ...

Regression Analysis - Regression analysis is a simple way to investigate the relationship between 2 or more variables in a non-deterministic way. Response/Target Variable (Y) - This is a variable we're interested in understanding, modeling or testing This is a random variable. It varies with changes in the predictor(s) 2. Predicting/Explanatory (independent) Variables(Xs ~ X1, X2) - These are variables we think might be useful in predicting or modeling the response variable This i...
