You could do a multivariate regression using mvregress. This is what it sounds like you are trying to do. I wouldn't recommend trying to extrapolate future values from a linear regression though. Other considerations include neural networks ( narxnet or narn...
I. R-Squared in R with Linear Regression In this example, we have implemented the concept of R square error metric on the Linear Regression model. Initially, we load our dataset using the read.csv() function. The next step is to segregate the data into training and test datasets. This ...
1. Explain the difference between simple linear regression and multiple regression? 2. Identify assumptions of multiple regression? 3. What is the general formula for multiple regression? 4. What is the difference between R^2 and R in multiple regressi In a simple...

2. And tada! We have successfully calculated the R-squared value in Excel. 3. Additionally, we can fit a simple linear regression to verify our calculations. Then, we will go to theDatatab and selectData Analysis. If you do not see this tool, you first need to install the freeAnalysis...
As we saw in section 2, when calculating margins based on a linear regression model, leaving a predictor variable “as observed” yields the same marginal mean as setting that predictor variable equal to its mean. When we specify atmeans, we are setting turn equal to its mean of 39.7971. ...
