Local variables can even be declared with the same name as a global variable. If this happens, there are actually two different variables with the same name: one local and one global. This helps ensure that an author writing a local variable doesn’t accidentally change the value of a global variable they aren’t even aware of.

The GROUPS subcommand specifies an unknown variable or a long string variable.

Paths are traversed in the order they occur in the search path. By default, this means the files in app/assets take precedence, and will mask corresponding paths in lib and vendor.

Understanding types of variables

Otherwise, please take the time to read about declarations hoisting (MDN, Adequately Good) and variable shadowing, as these concepts are key to fully understanding TDZ.

<!-- The . represents an element in $array -->

PHP variables begin with the dollar symbol $ and PHP variable names adhere to the following rules:• Names are case sensitive• Names may contain letters, numbers, and the underscore character• Names may not begin with a number

However, the gain ratio is the most important metric here, ranged from 0 to 1, with higher being better.

Feature predictive power will be calculated for all features contained in a dataset along with the outcome feature. Works for binary classification, multi-class classification and regression problems. Can also be used when exploring a feature of interest to determine correlations of independent features with the outcome feature. When the outcome feature is continuous of nature or is a regression problem, correlation calculations are performed. When the outcome feature is categorical of nature or is a classification problem, the Kolmogorov Smirnov distance measure is used to determine predictive power. For multi-class classification outcomes, a one vs all approach is taken which is then averaged to arrive at the mean KS distance measure. The predictive power is sensitive towards the manner in which the data has been prepared and will differ should the manner in which the data has been prepared changes.

Mutual information is one of many quantities that measures how much one random variables tells us about another. It is a dimensionless quantity with (generally) units of bits, and can be thought of as the reduction in uncertainty about one random variable given knowledge of another. High mutual information indicates a large reduction in uncertainty; low mutual information indicates a small reduction; and zero mutual information between two random variables means the variables are independent.
