Question: For a simple linear regression model:Yi=β0+β1xi+εloni,where i=1,cdots,n. Prove that if εloni and εlonj are uncorrelated, then Yi and Yj are uncorrelated,for i≠j. l Prove that ifare uncorrelated, thenand...

Common ratio (r) = \[\frac {a_2}{a_1} = \frac {a_3}{a_2} = \frac {a_n}{a_{n-1}}\] For example, the sequence 2,4,8,16,32… is a geometric sequence with a common ratio of 2 Common ratio (r) = \[\frac {4}{2} = \frac {8}{4} = \frac {16}{8} = \fra...
For example, A public health researcher is interested in social factors that influence heart disease. In a survey of 500 towns’ data is gathered on the percentage of people in each town who smoke, on the percentage of people in each town who bike to work, and on the percentage of people...
Owen, I tried the second Dax example from your first link (Other ways to use the pattern) and I seem to have created my trend line as desired! However, it has raised another question about the provided Trend Line provided in Analytics... I first added my new calculated trend line (yell...
I am trying to apply linear regression to the data below. Not sure its applicable with the multiple groups in the dosegrp column. Also, I imported the file as CVS. Its original form is excel. Is that why its not working? My file name is HAMA. One of the columns is HAMA. Do I ne...
