Statistical analysis results of muscle fiber counts.

FIBER_COUNT_STATS

Format

An object of class data.frame with 40 rows and 19 columns:

response

character; the measurement being tested. All "Fiber Count".

age

factor; the age of the rat at the beginning of the training protocol. Levels: "6M" (Adult) and "18M" (Aged).

sex

factor; the sex of the rat with levels "Female" and "Male".

muscle

factor; the muscle that was sampled with levels "LG" (lateral gastrocnemius), "MG" (medial gastrocnemius), "PL" (plantaris), and "SOL" (soleus).

balance

numeric; Exploring Compositional Data with the CoDa-Dendrogram: "the natural logarithm of the ratio of geometric means of the parts in each group, normalised by a coefficient to guarantee unit length of the vectors of the basis" (Pawlowsky-Glahn & Egozcue 2011).

contrast

factor; the comparison between groups. All contrasts are differences between the 8W and SED group means ("8W - SED").

estimate_type

character; interpretation of the value in the estimate column. All "difference of means" (difference between group means, as specified by contrast).

estimate

numeric; difference between the means of the groups as specified by contrast.

SE

numeric; the standard error of the estimate.

lower.CL

numeric; lower bound of the 95% confidence interval.

upper.CL

numeric; upper bound of the 95% confidence interval.

statistic_type

character; the type of statistical test.

statistic

numeric; the value of the test statistic.

df

numeric; the number of residual degrees of freedom.

p.value

numeric; the p-value associated with the statistical test.

p.adj

numeric; the adjusted p-value.

signif

logical; TRUE if p.adj < 0.05.

model_type

character; the statistical model used for testing.

formula

character; the model formula. Includes the response variable, any transformations, and predictors.
