On the tough balance between revisiting foundations & learning new tools
A recent read reminded me of the delicate balance - one I find myself continuously navigating - between strengthening core statistics & embracing the latest advancements (like tools that automate parameter selection & modeling). ๐๐ฟ๐ผ๐ป๐ถ๐ฐ๐ฎ๐น๐น๐, ๐ฎ๐ป๐ฑ ๐ผ๐ณ๐๐ฒ๐ป, ๐๐ต๐ฒ๐๐ฒ ๐ถ๐ป๐ป๐ผ๐๐ฎ๐๐ถ๐ผ๐ป๐ ๐บ๐ฎ๐ธ๐ฒ ๐ถ๐ ๐๐ฒ๐บ๐ฝ๐๐ถ๐ป๐ด ๐๐ผ ๐ณ๐ผ๐ฟ๐ด๐ฒ๐ ๐๐ต๐ฒ ๐ณ๐๐ป๐ฑ๐ฎ๐บ๐ฒ๐ป๐๐ฎ๐น๐ ๐๐ต๐ฒ๐โ๐ฟ๐ฒ ๐ฏ๐๐ถ๐น๐ ๐๐ฝ๐ผ๐ป.
How can I be a leader & keep up my technical skills at the same time?
While searching for the answer, I realized the TTGM framework. TTGM stands for Teach - Trust - Set Goals - Mentor. A mnemonic to remember it is Time To Gain Mastery.
Analytics to Decisions
How might organizations become more effective in converting analytics into management actions?
Confidence is a Choice
โConfidence is a choice, not a symptom. The batter has already hit two home runs. When he gets up to bat for the third time, his confidence is running highโฆ
Itโs easy to feel confident when weโre on a roll, when the cards are going our way, or weโre closing sales right and left. This symptomatic confidence, one built on a recent series of successes, isnโt particularly difficult to accomplish or useful.
Effective confidence comes from within, itโs not the result of external events. The confident salesperson is likely to close more sales. The confident violinist expresses more of the music. The confident leader points us to the places we want (and need) to go.
You succeed because youโve chosen to be confident. Itโs not really useful to require yourself to be successful before youโre able to become confident.โ
What is Econometrics?
My background is in Econometrics. I get asked this question a lot. Sometimes it comes directly, sometimes in puzzled stares. Sometimes in glazed eyes where theyโre regretting their first question for fear of a barrage of heavy statistical terminology. Letโs simplify it without the fear.
On the Visibility of Deep Thinkers
โWe pay too much attention to the most confident voices - and too little attention to the most thoughtful ones. Certainty is not a sign of credibility. Speaking assertively is not a substitute for thinking deeply.
Itโs better to learn from complex thinkers than smooth talkers.โ
Book Review: Becoming a Technical Leader, Ch 1
The Leadership Book Club, at R&D Mx, is sometimes hosted by motivated colleagues, sometimes by me. It is a great space to meet coworkers that I wouldnโt usually bump into. This time, we picked a book that takes us back to the basics (and, in doing so, invites many aspiring leaders) while promising to take us beyond the theory of most other leadership books: โBecoming a Technical Leaderโ by Gerald M. Weinberg.
On Ordering Correlograms
Correlograms are the usual go-to visualization for a correlation coefficient matrix. If your features set (set of variables in dataset) has only a few features, the human mind is able to eyeball the correlation co-efficients to glean the most important relationships. However, when the list of features is longer, eyeballing is time consuming and there are chances that we will miss out on a few unobvious but important details. As a rule of thumb, when the feature set contains more than 5 features, I prefer studying a corellogram rather than its correlation matrix for insights.
