1. > stackloss.lm = lm(stack.loss ~ + Air.Flow + Water.Temp + Acid.Conc., + data=stackloss)
2. > newdata = data.frame(Air.Flow=72, # wrap the parameters. + Water.Temp=20, + Acid.Conc.=85)
3. > predict(stackloss.lm, newdata) 24.582.

Can you do multiple regression in R?

Multiple regression is an extension of linear regression into relationship between more than two variables. In simple linear relation we have one predictor and one response variable, but in multiple regression we have more than one predictor variable and one response variable.

How to forecast double seasonal time series in R?

Forecast double seasonal time series with multiple linear regression in R – Peter Laurinec – Time series data mining in R. Bratislava, Slovakia. I will continue in describing forecast methods, which are suitable to seasonal (or multi-seasonal) time series.

What is the relationship between forecasting and linear regression?

Forecasting and linear regression is a statistical technique for generating simple, interpretable relationships between a given factor of interest, and possible factors that influence this factor of interest. The factor of interest is called as a dependent variable, and the possible influencing factors are called explanatory variables.
