I am trying to analyze this time series data from the Wooldridge Econometrics book containing weekly data on the New York Stock Exchange, beginning in the year 1976 January and ending in 1989.
I have never worked with the ts() function before but I understand the general grammar already. What I have difficulties with, is how I should define the frequencies since every 4th year has 366 instead of 365 days. In the book is already stated that for holidays or weekends, the following day was used, when the stock exchange was open.
So how do I exactly deal with this problem of creating a time series object?
Here is a screenshot of the first rows of the data frame: data frame of nyse
