Intercept:The expected value of the price of housing will be **39,954 Thousand US Dollars** when there is no pool, no living room, and no fire place in the house, there are no bathrooms, and the log of square feet is 0, which doesn’t make economic sense.  

The house has a pool: This is a dummy variable with 2 options: having or not having a pool. The difference effect in the price of housing is **5,198 thousand US dollars** on average between having or not having a pool in the house,

Properties of the Error Term in OLS

The Ordinary Least Squares (OLS) method relies on several assumptions about the model and the error term (u):

  • SLR.1: Linearity in Parameters. The model is linear in its parameters (coefficients).
  • SLR.2: Random Sampling. The data is obtained from a random sample of size n.
  • SLR.3: Sample Variation in the Explanatory Variable. The sample outcomes for the explanatory variable (X) are not all the same value.
  • SLR.4: Zero Conditional Mean. The error term u has an expected

Obstruents and Sonorants

The vowel-like nature of nasals, liquids, and semi-vowels necessitates the umbrella terms obstruent and sonorant. Obstruents are plosive, fricative, and affricate consonants. Sonorants comprise vowels, diphthongs, and other consonants with vowel-like qualities.

English Vowels

/i:/: Front, almost fully close, unrounded. Tends to diphthongize to (ij).

/ɪ/: Front, slightly retracted, close-half-close, unrounded. Used in endings like -ace, -age, -ate, -ness.

There are two main kinds of abstractions in programming languages:

  • Process Abstraction: A subprogram that provides a way to continue a process without revealing the underlying details.
  • Data Abstraction: A technique to separate the interface of a data type
