Gaussian kernel were used, so it is not optimal in any global sense. Strictly speaking cumulative density function is a contradiction in terms, but i have commonly seen it used to mean the distribution function. The scale scale keyword specifies the standard deviation. Access the normalcdf function on the calculator by pressing 2nd. The preceding articles showed how to conduct time series analysis in stata on a range of univariate and multivariate models including arima, var lag selection and stationarity in var with three variables in stata and vecm vecm in stata for two cointegrating equations. Time series data requires some diagnostic tests in order to check the properties of the independent variables. These functions mirror the stata functions of the same name and in fact are the stata functions. See probability distributions and density functions ind functions for function details. The below functions return density values, cumulatives, reverse cumulatives, inverse cumulatives, and in one case, derivatives of the indicated probability. Students t and noncentral students t distributions.
Density plots normal add normal density to the graph normoptscline options. So it is most likely that this is what the authors. Gaussian normal d normaldenz d normaldenx, sd d normaldenx, mean, sd p normalz z invnormalp lnd lnnormaldenz lnd lnnormaldenx. You may want to convert this number to a percentage.
