The command "grep -v ""inn"" sample1" displays all the lines in the file "sample1" that do not contain the exact string "inn". This command is different from the results in step 2 because it excludes lines with the specified string instead of including them.

The "grep" command is used to search for lines in a file that match a given pattern. In this case, the "-v" option is used, which tells grep to display all the lines that do not match the specified pattern. The pattern in this command is ""inn"", which is the exact string "inn" enclosed in double quotes.

When this command is executed on the file "sample1", it will display all the lines in "sample1" that do not contain the string "inn". If a line in "sample1" contains the string "inn", it will be excluded from the output. The command essentially filters out lines with the specified pattern and shows the remaining lines. This is different from the results in step 2 because in step 2, the command "grep ""inn"" sample1" displayed all the lines in "sample1" that contain the string "inn". In step 3, with the addition of the "-v" option, the command excludes lines with the specified string instead. So, the output will be the inverse of the output in step 2, showing lines without the string "inn" instead of lines with it.

In an autoregressive model, the explanatory variables are typically referred to as lagged values of the dependent variable.

This is because the model uses past values of the dependent variable to predict its future values. Specifically, an autoregressive model of order p (denoted as AR(p)) includes p lagged values of the dependent variable as explanatory variables. The model can be expressed as Yt = c + ϕ1Yt-1 + ϕ2Yt-2 + ... + ϕpYt-p + εt, where Yt represents the dependent variable at time t, c is a constant term, ϕ1-ϕp are the autoregressive coefficients, Yt-1 to Yt-p are the lagged values of Yt, and εt is the error term. The autoregressive coefficients represent the impact of past values of the dependent variable on its current value, while the error term captures the effect of unobserved factors that affect the dependent variable.
