Market trend. A market trend is a perceived tendency of the financial markets to move in a particular direction over time. [1] Analysts classify these trends as secular for long time-frames, primary for medium time-frames, and secondary for short time-frames.

The golden ratio's negative −φ and reciprocal φ−1 are the two roots of the quadratic polynomial x2 + x − 1. The golden ratio is also an algebraic number and even an algebraic integer. It has minimal polynomial. This quadratic polynomial has two roots, and. The golden ratio is also closely related to the polynomial.
Monte Carlo method. The approximation of a normal distribution with a Monte Carlo method. Monte Carlo methods, or Monte Carlo experiments, are a broad class of computational algorithms that rely on repeated random sampling to obtain numerical results. The underlying concept is to use randomness to solve problems that might be deterministic in ...
Pearson correlation coefficient. Several sets of ( x , y) points, with the correlation coefficient of x and y for each set. The correlation reflects the strength and direction of a linear relationship (top row), but not the slope of that relationship (middle), nor many aspects of nonlinear relationships (bottom).
t. e. In statistical modeling, regression analysis is a set of statistical processes for estimating the relationships between a dependent variable (often called the 'outcome' or 'response' variable, or a 'label' in machine learning parlance) and one or more independent variables (often called 'predictors', 'covariates', 'explanatory variables ...
Pronunciation and etymology The name, "Yen", derives from the Japanese word 圓 (en, ; "round"), which borrows its phonetic reading from Chinese yuan, similar to North Korean won and South Korean won.Originally, the Chinese had traded silver in mass called sycees, and when Spanish and Mexican silver coins arrived from the Philippines, the Chinese called them "silver rounds" (Chinese: 銀圓 ...
