Rindex.

An index that can be used with any R-vector x of length n needs to store the original values together with the original positions, i.e. list (val=x, pos=order (x)), thus requires -- strongly simplified -- 2 ∗ n RAM. If we store this information in a binary tree, each value pair {val,pos} is stored in its own node together with two pointers ...

Rindex. Things To Know About Rindex.

To carry out this operation, Python provides us with a string handling function. Python rfind () is used in such cases. Python rfind () function is used to return the highest index value of the last occurrence of the substring from the input string; else it returns -1. Python rfind () function follows the below-mentioned syntax:string = "21135" reverseindex = string.rindex(1) # reverseindex == 2 But lists don't have this function. Share. Improve this answer.

The value of R-index ranges between 0% and ... The success rate for the original studies was 100% (one study had a marginally significant effect, p < .10, two-tailed). Median observed power was 86%. The inflation rate is 100 – 86 = 14, and the R-Index is 86 – 14 = 72. Thus, an R-Index of 72 suggests that studies have a high probability of replicating.
