If you do choose a low-carb diet providing less than 130 grams of carbs, only do so under medical supervision. Because carbohydrates attach to water in your body, low-carb diets often lead to water-weight loss. Therefore, you may notice weight loss from water, not body fat, after just a day or two of low-carb dieting.If youâre dieting safely on your own without medical supervision, youâll likely start to notice weight loss in about a week.iets containing 800 calories -- or less -- per day are classified as very low-calorie diets. Although you can lose weight rapidly using this type of diet, you should only do so under close supervision by a qualified health care provider.
The greater the absolute value of a correlation coefficient, the stronger the linear relationship. The strongest linear relationship is indicated by a correlation coefficient of -1 or 1. The weakest linear relationship is indicated by a correlation coefficient equal to 0. A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.
The linear correlation coefficient is the ratio between the covariance and the product of standard deviations of both variables. The linear correlation coefficient is denoted by the letter r. r = $\frac{Cov(X, Y)}{\sigma_x \sigma_y}$. Correlation coefficient will always lie between -1 and +1.
