Let’s talk about estimation.

Level Up Coding

I struggled a lot with estimations in my two years as a developer. And I’m not the only one, most of my coworkers struggle with this too. I think it’s because nobody teaches you how to estimate when…

Estimate Smarter, not Harder

Better Programming

One of the most difficult (and paradoxically time-consuming aspects) of a software developer’s job is estimation. When developers make estimates about their work it can affect the success of the…

How to Make Better Estimates?

Level Up Coding

Estimation provides business value. Accuracy in estimation can lead to better budgeting. You can estimate the cost of work, schedule releases with ease, and correct project planning. Software…

How to Get Better with Estimations

Towards Data Science

Estimations are hard. Every developer struggles with that task. The reason for that is simple: developers are asked to estimate something that they never did before. Unless it is an agency that makes…...

Estimation, Prediction and Forecasting

Towards Data Science

Estimation implies finding the optimal parameter using historical data whereas prediction uses the data to compute the random value of the unseen data. Estimation is the process of optimizing the…

You probably don’t need to estimate. Just count the tickets.

Level Up Coding

Look, estimates are useful, ok? They are useful for making product decisions, they are useful for managing expectations, they are useful for planning resource. But developers hate estimating. At least...

Advantages Similar to a tf.keras.Model , an estimator is a model-level abstraction. The tf.estimator provides some capabilities currently still under development for tf.keras . These are: Parameter se...

Agile Estimation: part II

Towards Data Science

In my previous notebook I proposed to use Poisson distribution for estimating the number of story points per iteration, i.e. project velocity. It is a fairly simple distribution, which has one…

Plain and Simple Estimators

Towards Data Science

Machine learning is awesome, except when it forces you to do advanced math. The tools for machine learning have gotten dramatically better, and training your own model has never been easier. We’ll…

The main goal of statistical inference is learning from data. However, data we want to learn from are not always available/easy to handle. Imagine we want to know the average income of American…

Why Estimates Are Waste

The Consistent Estimator

Towards Data Science

A consistent estimator is one which produces a better and better estimate of whatever it is that it’s estimating, as the size of the data sample it is working upon goes on increasing.
