What is a random walk model and how can you simulate it using r?..

Answer / Mr Vinod Kumar

A random walk model is a type of stochastic process where the movement or change in a variable at any given time depends on its previous state. It is often used to represent price movements in financial markets. In R, you can simulate a random walk using the `arima.sim()` function with specific parameters:nn```Rn set.seed(123)n n <- 100n drift <- 0.05n sd <- 0.1n data <- arima.sim(n = n, model = list(ar = c(1), ma = c(0)), sd = sd + drift * sqrt(n))n```
