The thicker the insulation is, the greater the R-Value. K-Value on the other hand is the measure of heat conductivity of insulation. ... For example, the higher the R-Value the greater the insulating performance of the material, whereas the opposite is true for K-Value.

r-selected babies grow rapidly, and tend to be found in less competitive, low quality environments. ... K-selected species produce offspring that each have a higher probability of survival to maturity.

Kp=Equilibrium constant in terms of partial pressure. Kc=Equilibrium constant in terms of concentration. Kx=Equilibrium constant in terms of mole fraction. Kn=Equilibrium constant in terms of number of moles.

R-squared measures the proportion of the variation in your dependent variable (Y) explained by your independent variables (X) for a linear regression model. Adjusted R-squared adjusts the statistic based on the number of independent variables in the model.

R-squared measures how closely each change in the price of an asset is correlated to a benchmark. Beta measures how large those price changes are in relation to a benchmark. Used together, R-squared and beta give investors a thorough picture of the performance of asset managers.

the difference is that print_r print an array, showing all keys and values,while echo doesnt,and is intended for scalar values.. echo used to print string or HTML content while as print_r used to print an array object means both keys and values.

The main difference between nominal and real values is that real values are adjusted for inflation, while nominal values are not. As a result, nominal GDP will often appear higher than real.

Kc and Kp are the equilibrium constants of gaseous mixtures. However, the difference between the two constants is that Kc is defined by molar concentrations, whereas Kp is defined by the partial pressures of the gasses inside a closed system.

While U-value is used to measure the performance assemblies such as IGUs, R-value is used to measure the performance of most other parts of the building envelope, such as walls, floors and roofs. ... Thus, while lower U-values indicate better insulating performance, higher R-values indicate better thermal resistance.

K means thousand(or any number N followed by 3 zeros). It is short for “kilo”. ... As such, people occasionally represent the number in a non-standard notation by replacing the last three zeros of the general numeral with "K": for instance, 30K for 30,000.

Simply put, R is the correlation between the predicted values and the observed values of Y. R square is the square of this coefficient and indicates the percentage of variation explained by your regression line out of the total variation. This value tends to increase as you include additional predictors in the model.

'K' stands for "kilo-", which means thousand. e.g. $1.8k means $1,800.

The key difference between r strategist and K strategist is that the r strategist lives in unstable and unpredictable environments while the K strategist lives in more stable environment. Because of this environmental conditions, the r strategists produce many offspring while the K strategists produce few offsprings.

The constant value (often written k) relating amounts that rise or fall uniformly together. It is the ratio of the amounts y and x: k = y/x. Put another way: y = kx.

Simply stated: the R2 value is simply the square of the correlation coefficient R . The correlation coefficient ( R ) of a model (say with variables x and y ) takes values between −1 and 1 . It describes how x and y are correlated.

A positive RD value means increased risk and a negative one means decreased risk by the exposure. ... An OR value of 1 means no difference in odds between groups, and larger value than 1 means increased odds in exposed group, interpreted as a positive association between having disease and having exposure.

The most common interpretation of r-squared is how well the regression model fits the observed data. For example, an r-squared of 60% reveals that 60% of the data fit the regression model. Generally, a higher r-squared indicates a better fit for the model.
