In this paper we propose a prediction model based on time series involving EWMA type approach. After a brief historical sketch and a short presentation of the GLM - General Linear Model we construct the predictor which is an average exponentially weighted depending on previous and current values of the series. The last paragraph is dedicated to an analogy with SPC - Statistical Process Control and possible applications are emphasized. Open theoretical problems are discussed also.
