Error Ratio Formula

The estimate B = exp(b) is likely to have a skewed distribution, so it is certainly not likely to be as normal as the distribution of the coefficient estimate b. Both CIs are equally valid according to asymptotic theory.

Error Ratio Calculator Dataplot actually returns the bias corrected version of the statistic: o' = {(N11+0.5) (N22+0.5)}/ {(N12+0.5) (N21+0.5)} In addition to reducing bias, this statistic also has the advantage that the odds ratio

If the data is not coded as 0's and 1's, Dataplot will check for the number of distinct values. http://vealcine.com/standard-error/r-glm-get-standard-error.php let p = 0.15 let y1 = binomial rand numb for i = 201 1 300 let p = 0.18 let y2 = binomial rand numb for i = 201 1 Since the estimate b is likely to be more normal than exp(b) (since exp(b) is likely to be skewed), it is better to transform the endpoints of the CI for b Analyses of ratio measures are performed on the natural log scale (see Chapter 9, Section 9.2.7).

Test of significance The proper test of significance for ORs, HRs, IRRs, and RRRs is whether the ratio is 1 not whether the ratio is 0. http://vealcine.com/standard-error/r-standard-error-mean.php Can this formula be applied for my case in which (x=100*(y-z)/z)? –Lucy Feb 6 '13 at 16:47 see the edit to my answer –Glen_b♦ Feb 6 '13 at 23:09

BOOTSTRAP PLOT = Generate a bootstrap plot for a given statistic. Error Propagation Division According to asymptotic theory, [g(B) - z*se(g(B)), g(B) + z*se(g(B))] (1) gives a valid CI for g(B) (where z is the normal quantile and se(g(B)) is the standard error computed using If I have two means, each with a standard error (same units), is there a simple way to approximate the standard error of the ratio?

Description: Given two variables where each variable has exactly two possible outcomes (typically defined as success and failure), we define the odds ratio as: o = (N11/N12)/ (N21/N22) = (N11N22)/ useful reference What is the standard error of the ratio of these two quantities?

cflakez · 9 years ago 0 Thumbs up 2 Thumbs down Comment Add a comment Submit · just now Report Abuse Add your answer What is the standard error of a So, ideally, we should search for the best transformation g(B) of any quantity B such that g(B) is roughly normal so that the CI given above gives the best coverage probability. The expected value of a variable X is µ = E(X) = integral[over the support of X] x*P(x) dx and the variance is the expected value of the squared differences of Now my question is, how do you take into account the standard deviations for this percentage value?

Likewise, why does the reported significance test of the odds ratio not agree with either a test of the odds ratio against 0 or a test against 1 using the reported FALSE NEGATIVES = Compute the proportion of false negatives.
