Hello everyone!
I am working on a stock trading algorithm. I have created a data frame with
the stocks, and a summary data frame, master_df_ex, and master_df_ex_sum,
respectively.
The goal is to create something each day that has equal long and shorts,
and thus for each day, the sum of the ls_fla

Hi there,I am working on a time series dataset with a lot of missing data
(around60%).Specifically, I need to fit an ARIMA model to this data and I found
thatExpectation-Maximization (EM) algorithm using Kalman filter could
beusefull.Anyone know if already exist a package for this?Another approa

Lmer has never returned p-values from a model summary; this is a well-known and
discussed issue. You must have post-processed the data in some way to get the
p-values.
Our only way of helping is for you to provide sample code on what you did

Hello
Can one calculate the month number between two dates
D1 <- "01/01/2007" and D2 <- "01/04/2009" ?
Thank you
One way is through zoo's yearmon class:
R> library("zoo")
R> D1 <- as.yearmon("01/01/2007", format = "%d/%m/%Y")
R> D2 <- as.yearmon("01/0
