I'm currently studying the length-weight relationship of freshwater fishes in Taiwan, which is an all new topic for me to work on. However, I've came across problems in calculating the 95% confidence interval and confidence limit for my parameters a and b in the LWR formula W=aL^b that I do not understand how. Publications I've viewed gives little info and couldn't actually help me out, so is anyone here able to help me to understand and calculate these parameters?
The problem for me is that I do not understand how I can gain the CI and CL from a single data since all publications mentioned "95% CI of b".
To calculate the confidence limits for a measurement variable, multiply the standard error of the mean times the appropriate t-value. The t-value is determined by the probability (0.05 for a 95% confidence interval) and the degrees of freedom (n−1) :)
A CI of 95% means that 95% of the values are within the interval. These are statistics, maybe this can help? https://en.wikipedia.org/wiki/Confidence_interval
Thanks for the help on my question from Andrew and Arne, I've already figured out the solution and finished my work, cheers !
