Hi! i am looking for mathematical stats book recommendations for noncentral distributions. I am currently using "Hand-book on STATISTICAL DISTRIBUTIONS for experimentalists" and "Handbook of Statistical Distributions with Applications" but both the free-ebooks do not provide proofs.
Please help me prove that the pdf of a noncentral t distribution is a valid pdf. That is, to prove that the integral of the pdf of noncentral t distribution from negative infinity to infinity is 1. The attached document contains my attempt.
Which of the following definitions is incorrect?
It is a process by which sample data is used to estimate or approximate the value of an unknown population parameter.
The estimate can be expressed as a single value, known as a point estimate, or a range of values, known as an...
What is the difference between a residual and an error?
Is it wrong to say an error is the difference between the data points and a fitted line while a residual is the difference between data points and the sample mean.Please help!!
Are there any statistical tests that i can use to evaluate whether the assumptions for the regression model are being met?
The assumptions i want to test are:
1. The model adequately describes the behaviour of the data.
2. The random error term is an independently and normally...
