I need timed live help session with the statistics problem of time series analysis

I need timed live help session with the statistics problem of time series analysis. it will cover: 1) Weakly and strictly stationary time series; how to compute ACF and ACVF of stationary time series; how to identify non stationary time series. 2) AR(1) and MA(1) time series; confidence intervals for the mean and ACFs of MA(1) and AR(1) time series 3) How to identify nonnegative definite functions using ACVF of stationary time series 4) Sample ACF and ACVF and confidence intervals of ACFs 5) How to compute the best linear predictor
