I always get excited when I see these "tutorials for dummies" (like me). Like "finally, I get to take an evening to understand this concept that's eluded me for years." Generally, I get let down. This time is no exception.
They always start off well, then inevitably there's a concept or key terminology that gets glossed over without sufficient explanation. .
"The random variable is described by the probability density function. The probability density function is characterized by moments.
The moments of the random value are expected values of powers of the random variable. We are interested in two types of moments"
This is where my journey ended this time. OK, so is that the expected value of the expontnent.of the random value orthe expected value of the random value to some power... and what makes the power of a randome value so special vice just operating on the randome value itself.
It's like these authors get tired of "dumbing" things down at random points in their chain of thought and just decide to skip over stuff. Or, perhaps they don't understand the underlying concepts themselves and simply can't explain them to others.
Who knows. Just frustrating. At least in Udemy you can write to instructors and ask questions. Unlike a book author who aren't paid to respond.
