Therefore, any test of market efficiency or of a pricing model is in fact a JOINT test and you will never know if the pricing model is wrong or the market is not efficient. Of course, for the weak ... Value-at-risk measures apply time series analysis to historical data 0 r, –1 r, –2 r, … , –α r to construct a joint probability distribution for 1 R.They then exploit the functional relationship θ between 1 P and 1 R to convert that joint distribution into a distribution for 1 P.From that distribution for 1 P, value-at-risk is calculated, as illustrated in Exhibit 1 above. F-test is any type of statistical test that uses an f-statistic or f-value, which is the ratio of any two sample variances and has an f-distribution within the null hypothesis testing. In ANOVA or analysis of variance, f-tests are frequently used in a statistical capacity to determine the equality of different means when there are three or more groups involved by evaluating the variations both ... Stationarity: A stochastic process is called stationary if the mean and variance are constant (i.e., their joint distribution does not change over time). We start our analysis by plotting our time series object to give us a visual basis to start our modeling. plot_time_series(sp500_training, 'S&P 500') You can easily see that our time series has instances of both positive and negative trend ...
