The correct statements are:
Based on the range of values of Y, it is harder to assume that the noise is Gaussian.
Mathematically, linear regression is impossible to compute for Yes/No responses.
Mathematically, linear regression is impossible to compute for integer-valued features, (e.g. [mathjaxinline]X_1[/mathjaxinline] = the number of missed flights).
Explanation:
1. The range of values of Y is bounded: This statement is not necessarily true. The range of values of Y may or may not be bounded depending on the specific problem and data.
2. The range of values of [mathjaxinline]\mu[/mathjaxinline] is strictly positive: This statement is not necessarily true. [mathjaxinline]\mu[/mathjaxinline] represents the expected value of Y, and it can be any real number, including negative or zero values.
3. Based on the range of values of Y, it is harder to assume that the noise is Gaussian: This statement is true. If the range of values of Y is limited (e.g., bounded between 0 and 1 for a Yes/No response), it is harder to assume that the noise follows a Gaussian distribution, which is typically assumed in linear regression.
4. Mathematically, linear regression is impossible to compute for Yes/No responses: This statement is true. Linear regression assumes a continuous target variable, and it cannot be directly applied to Yes/No responses. Instead, methods like logistic regression or other classification algorithms should be used.
5. Mathematically, linear regression is impossible to compute for integer-valued features: This statement is true. Linear regression assumes that the predictors (features) are continuous variables. If the features are integer-valued, linear regression cannot be directly applied. Different regression techniques, such as generalized linear regression, may be more appropriate.
