For all viewers I suggest R in data-analytics! Not Python!!

Hey mate, I am actually cursed and keep missing your lives do you mind if I ask you here? Or would you like me to wait for the next live?

@GregHogg 2 года назад

Haha no problem; feel free to ask a question here.

@@GregHogg hey mate, thanks for this opportunity! First of all, I hope that you're doing great! secondly, This question might take some time, and I think that there are other people like me. background: non-math/stat/anything that is worth it related 'biology' programming skills: zero (I just started learning python) Goal: basically make money by working online. My question is, is it worth it learning data analytics/science if my only purpose is to make money as a freelance or remote worker? What will separate me from millions of other data scientists/analysts (by the time I finish learning, I would have a "meh" portfolio) and I am sure that there would be at least 100.000 other people in India that are better than me (I learn from them lol) so how can I compete? I know that nationality plays a big role in landing a remote job (seen it with my own eyes xd) and mine kind of sucks 'even traveling abroad is out of the question since I have a weak passport.' Thanks for reading this!

27:00 in accuracy score, first arg is y_actual, 2nd arg is y_pred. You passed the other way round. LMAO

@GregHogg 2 года назад

The order of these two doesn't matter :)

@tiagosilva856 Год назад

@@GregHogg doesn't matter in this example cuz phyton can understand it. But it really matters in reality. The functions arguments should be called in the right order.

@commonsense1019 2 года назад

plzz use dark mode if possible

@GregHogg 2 года назад

Haha okay

The video is very good. Although he didnt have the mathematical knowledge to explain what the coeficient and the intercept means in a logistic regression. As a senior data scientist i give this free for youtube community. the coeficient tell us how much the probability of having heart disease increase or decrease when we go up in x by 1.0 value (max HR in this example ). In this case we can see that for every 1.0 increase in MaxHR the probability of having Heart Disease decrease about 3%. The intercept tell us the probability of having heart disease when the x=0 (maxHR=0), ofc in this case dont make any sense, because if u have 0 heart rate you would be dead. Although the model says you have 500% probability of having heart disease. Maths its the base to understand ML phyton and modules are tools. You can never make a proper analize of an ML output if you dont understand maths.
