Is date a dependent variable?
Dependent Variable Is a Date. But NeuralTools does standardize numeric variables, so there’s no need to worry about those date values being incommensurate with the independent variables. There are no restrictions associated with using dates in NeuralTools cases.
How do you make a variable a date in R?
To create a Date object from a simple character string in R, you can use the as. Date() function. The character string has to obey a format that can be defined using a set of symbols (the examples correspond to 13 January, 1982): %Y : 4-digit year (1982)

How to use time series modeling in R?
Take a look, it’s a fantastic introduction and companion to applied time series modeling using R. -library, which provides a convenient wrapper for linear models with timeseries-data. The function provides two shorthands to add trend – and season -variables as regressors, which is quite useful to avoid problems such as “spurious regression”.
When to use linear regression on a date variable?
Usually, but not necessarily, the origin should be a date within the time period of study or very close to it. Perhaps the simplest case is linear regression on a date variable in years. Here a regression of some response on date expressed as dates like 2000 or 2010 implies an intercept which is the value of response in year 0.
