(redirected from intrinsic rate)
Also found in: Dictionary, Thesaurus, Medical, Financial, Encyclopedia.


Value, measure, or degree; a charge, payment, or price determined through the application of a mathematical formula or based upon a scale or standard.

For example, an interest rate is determined by the ratio between the principal and interest.

Rate is also used synonymously with tax.

RATE. A public valuation or assessment of every man's estate; or the ascertaining how much tax every one shall pay. Vide Pow. Mortg. Index, h.t.; Harr. Dig. h.t.; 1 Hopk. C. R. 87.

For the deterministic models, we explored the occurrence of long-term cycles by plotting regions of values of the intrinsic rates of increase [r.sub.y] and [r.sub.z] that produce tori [ILLUSTRATION FOR FIGURE 2 OMITTED].
Most importantly, again the intrinsic rate of increase was not statistically significant for any of the traits in either treatment (P [greater than] 0.11) and five of the six coefficients were positive, opposite that expected if a cost existed.

For each plant, Md and d were calculated, using the method of (Birch 1948) rm = 0.738 (log e Md) / d, the mean intrinsic rate of increase (rm) for each plant was calculated, where Md is the total number of progeny produced by [P1] the mother of F1, (d) is the time taken by F1 aphid from its birth till the production of its 1st offspring.

Based on these data, the intrinsic rate of natural increase ([r.sub.m]), was calculated by iteratively solving the equation (Birch 1948):
