uestion 1 
Airplanes arrive at gate no. 12 of a busy airport. After being parked in the right position, the passengers’ baggage gets unloaded by a 
team of baggage handlers. There is space for one airplane at the gate, and an unlimited space on the runaway for planes to wait for 
unloading. The arrival of planes follows a Poisson process with rate of 1 every hour. The unloading time of a plane is exponentially 
distributed, with rate proportion...

In a greenhouse experiment with several predictors, the response variable is the 
number of seeds that germinate out of 60 that are planted with different treatment 
combinations. A Poisson regression model is most appropriate for modeling this 
data - False - poisson regression models rate or count data. 
The R-squared and adjusted R-squared are not appropriate model comparisons for non linear regression 
but are for linear regression models. - TRUE - The underlying assumption of R-squared

Least Square Elimination (LSE) cannot be applied to GLM models. - Answer-False - it is applicable but 
does not use data distribution information fully. 
In multiple linear regression with idd and equal variance, the least squares estimation of regression 
coefficients are always unbiased. - Answer-True - the least squares estimates are BLUE (Best Linear 
Unbiased Estimates) in multiple linear regression. 
Maximum Likelihood Estimation is not applicable for simple linear regression and multiple ...

Logistic regression is different from standard linear regression in that: correct answers It does not have an error term; The response variable is not normally distributed; It models probability of a response and not the expectation of the response 
 
Logistic regression models correct answers The probability of a success given a set of predicting variables 
 
In logistic regression correct answers The estimation of the regression coefficients is based on maximum likelihood estimation
