See my post here for an explanation of how to understand the disturbance terms in a MA series. You need different estimation techniques to estimate them. This is because you cannot first get the residuals of a linear regression and then include the lagged residual values as explanatory variables because the MA process uses the residuals of the current regression.
Under this scenario, if planning poker is played with the whole team, the first round should reveal a wide disparity in story point estimates between team members. This doesn’t always happen when team members are “influenced” by each other’s estimates. Planning poker works only because of the discussions teams have around the disparity in their estimates.
What is planning poker estimation - Tips for using planning estimate effectively? It is an estimation technique and a discrete scaling method. It is played using the cards that are represented as modified Fibonacci series. Lets us explain with an example. When a task requires 2 weeks for completion, then the estimator will choose either a card with 13 or 20. Each estimator will open their.Estimation Poker helps frame estimation this way by acknowledging that uncertainty exists and increases as the perceived amount of effort increases. The non-linear estimation scales are a way to reinforce this. Estimation Poker is a conduit for surfacing assumptions, complexity, and risk.I am trying to create a synthetic time series where PSD estimation is necessary and useful to recover the correct spectral information of the time series. But so far I can only create a time series where either a) Fourier transform is superior and recovers sharper peaks; or b) Neither Fourier transform or PSD recover useful spectral information. I have been trying to show this by creating a.

Agile estimation is fundamentally different from conventional waterfall estimation. Waterfall tends to be “bottom up” while Agile is “top down”. The waterfall approach for estimating projects is to spend several weeks or months at the beginning of a project defining the detailed requirements. Tasks are defined and resources are assigned to tasks. The detail must be defined before cost.Read More
If a series of consecutive numbers are used, the team may end up invariably equating it to days or hours trying to thrust accuracy into the estimation process. However, as a variation, Planning Poker can be used for Sprint Backlog estimates as well, in which case, more accurate estimates are possible since the user stories picked up for the sprint at this stage would be more detailed and clear.Read More
The Planning Poker is a consensus based technique and is used to size the stories (in terms of story point) or effort estimate (in terms of days). It is a non-liner scale of estimation technique. Fibonacci series is used while playing the planning poker with higher numbers rounded off (0, 0.5, 1, 2, 3, 5, 8, 13, 20, 40, 60, 100). For example: You have been asked to provide your estimate for a.Read More
The Fibonacci series is just one example of an exponential estimation scale. The reason an exponential scale is used comes from Information Theory. The information that we obtain out of estimation grows much slower than the precision of estimation. In fact it grows as a logarithmic function.Read More
Consider a discrete sequence of values, for lag 1, you compare your time series with a lagged time series, in other words you shift the time series by 1 before comparing it with itself. Proceed doing this for the entire length of time series by shifting it by 1 every time. You now have autocorrelation function.Read More

Example of estimation vs. calibration. Ask Question Asked 8 years, 7 months ago.. Model estimation is the process of picking the best (according to some metric) kind and structure of model. Estimation may include calibration. Calibration is the process of finding the coefficients that enable a model (the kind and structure of which is already determined) to most closely (according to some.Read More
