Stata’s most obvious command for calculating moving averages is thema()function ofegen. Given an expression, it creates a #-period moving average of that expression. By default, # is taken as 3. # must be odd. However, as the manual entry indicates,egen, ma()may not be combined with...

ewma calculates an exponentially weighted moving average of the series named in the generate() option. This is kept in the archive only for any users of Stata 5.0. Users of Stata 6.0 upwards should instead install the egenmore package, including the ewma( ) function, which requires and respect...
In later test statements, you could refer to the coefficient on the first lag of the autoregressive term by typing [ARMA] b[L1.ar] or simply [ARMA] b[L.ar] (the L operator is assumed to be lag 1 if you do not specify otherwise). The second lag on the moving-average term, if ...

The data of daily confirmed new COVID-19 cases from February 15 to October 16, 2020, were collected from the official website of Our World in Data to construct the autoregressive integrated moving average (ARIMA) model and to predict the trend of the daily confirmed cases through STATA 13 ...
The Statalist archives are not a good place to look for commands. Try -findit- first. "findit moving average" would have turned up -movag- at SSC. If -findit- had not been successful. then a second step would have been to Google "Stata moving average". Steve On Nov 4, 2012, ...
